Anti-Aging Pt 4 - Mitochondria - User Manual For Humans S1 E20 - Dr Ekberg
good to see you guys again thanks for
coming I'm excited about this is kind of
a fun topic it's got a few corks to it
and it relates very much to health again
and aging this is a fourth installment
and we'll talk about mitochondria
they're usually described as the power
plant of the body of the cell and they
do a few other things as well that I'm
not going to get into
but the main thing they do is produce
energy
and I just want to bring up what we
quote that's the same slide from from
last time the two causes of degeneration
and there's a quote from a book by a
neurologist Dr Pearl Mater
it says the same forces that age your
body or aging your brain only they hit
your brain earlier and harder
these culprits are at the core of
virtually all brain degeneration from
mild memory issues to Alzheimer's
and the two reasons are the
proliferation of destructive chemicals
called free radicals which we talked
about last time and then two the decline
in the ability of the brain to make
energy
and that's what we'll talk about today
because these two things put together
creates a low-grade inflammation which
is the true mechanism for virtually all
degenerative disease
when we talk about the the brain and the
nervous system we talk about telomeres
the way that they get damaged is because
of free radicals and because we don't
have enough energy to to deal with it
so we will talk about energy today
and just a few terms
people talk about metabolism and that's
that's a common term uh we'll we'll
introduce also anabolism which simply
means to build up
catabolism which means to break down and
metabolism is just transform it's taking
some basically taking food and turning
it into energy and and body parts that's
metabolism
just a little side note here because
we're talking a lot about stress and and
brain
anabolism building up can only happen
from the parasympathetic
that portion of redu rebuilding
repairing building stuff really only
works all the way when we're in the
parasympathetic or relaxed mode
and catabolism break down that's when
we're stressed
and
when we are stressed the body doesn't
care about anything else than to survive
that moment
so it's not going to worry about healing
anything it's not going to worry about
fighting infections it's not going to
worry about digesting food it just wants
to get away from that grizzly bear so in
those moments you're in a catabolic
State you'll break down you'll sacrifice
anything
it's kind of like a steamship where
they're trying to get a little more
speed out of the engine and they're
running out of fuel so they start
breaking pieces off the boat and feeding
it to the flames
it doesn't make sense in the long run
but it makes sense in an emergency
so that's kind of what the body is doing
also
and when we talk about the food that we
eat they talk about we need so many
calories and we need fresh air to
breathe and we need oxygen and all that
we don't really need those things per se
we don't need oxygen we just need oxygen
because it can produce energy for us we
don't need calories we just need the end
result of the calories and the oxygen so
we don't use those things directly we
use the end result of them and that end
result and I just bring that point up
because the end result is what we're
going to talk about today when we talk
about energy
in the body there's only one kind of
energy it's called ATP
and we'll write that out for you it's
it's in the note
ATP
it's too long to write the whole thing
it stands for adenosine triphosphate
and this is in constant Exchange
with ADP
which is
adenosine diphosphate
so as you can see on slide number four
there is
in triphosphate that lasts that third
phosphate it's like it's jammed onto the
molecule with a high energy Bond
and that high energy bond is where we
get all of our energy it's the only
energy that the body can use outright it
fuels all of the the the
reactions and mechanisms and your
movement and your digestions and moving
things it does everything
and the energy that we get is when that
high energy bond is released
and ATP turns into ADP when that third
phosphate is shut off is locked off we
release energy
and that
doesn't sound like a big deal but that's
all the energy that we ever get
is from that reaction
and that's the same for autobiology it's
that that is the mechanism for getting
stuff done what is this is a molecule
yes okay yes so
ATP is a molecule exactly and it doesn't
look like the squares but my PowerPoint
skills are limited
that's when it comes to drawing
molecules
and then the body recycles this all the
time so we'll get to that
so what is this energy used for
there's three categories membrane
transport motility or muscle contraction
and biosynthesis none of these happen by
themselves so signaling
is what the brain does and it's
basically a signal happens when ions
Rush across a membrane and then we need
ATP to pump them back Upstream so that
they can do it again and we keep pumping
keep pumping that alone accounts for 20
percent of all the energy that you use
twenty percent of all the calories and
all the oxygen that you ever in take in
goes to that alone just pumping those
ions back across the membrane to make
signaling possible
and then we need it for absorption for
digestion and digestion is involved with
all three of these because digestion
uses membrane transport to bring
foodstuffs across the membrane in the
gut
uh it uses muscle contraction to move
the stuff along and for digestion the
peristalsis
and digestion uses biosynthesis to put
the stuff back together
into forms that that are usable for the
body
and digestion uses as much as 35 percent
of all of your energy so so far we've
used 55 of your energy and you haven't
done anything yet
that's kind of funny
we think that we oh I'm so tired I used
up all my energy well the energy that we
use for moving around isn't even half of
the energy needed in the body to just
keep things behind the scenes going
and muscle contraction that's any kind
of movement big or small so that's the
big voluntary movements it's exercise
but it's also again digestion and things
like vasoconstriction which means
regulating blood flow and and blood
pressure
biosynthesis
your immune system
has whenever you get an infection your
immune system has to manufacture
white blood cells and immune cells of
the specific kind that you need to fight
off that infection so when you're sick
you usually get extremely tired and it's
because now all that energy goes into
making those immune cells and that's a
very very expensive process you're
making a whole lot of them
DNA RNA proteins growth repair healings
all of those molecules that you use for
for processes in the body and for the
tissue itself they have to be
manufactured that doesn't happen by
itself either and then of course you
have to make molecules like
neurotransmitters and hormones and
digestive enzymes and digestive enzymes
are also very expensive that's a very
very energy intense process and that's
also why we get tired after after a big
meal
so how much ATP do we need these things
are really really small
they're they're molecules
so you use 25 million units of ATP per
cell per second
that's a pretty enormous number
every cell every second so that makes
about 2.2 trillion units of ATP per cell
every day
and then you have about a hundred
trillion cells
so that makes about
10 to the 28th molecules worth
but another interesting fact is that at
any given moment you only have about
three to four seconds worth of ATP
so if you do an all-out Sprint
then you're going to run out of ATP in
about three to four seconds and whatever
you rely on after that is lactic acid
plus ATP that your body makes from that
point on
so this supply of ATP is that
short-lived that whatever you're using
this minute you didn't have last minute
and
every 24 hours this this ATP ADP is
recycled anywhere from a thousand to
fifteen hundred times probably more if
you if you exercise
so when you add all this up you recycle
some 10 to the 28th to the power 28th
molecules of ATP and the sun if you were
to it's not like that it leaves or
comes into the body but the total weight
of that is about 200 400 pounds 200
kilos worth of ATP every day
and who does all this
this is where it gets kind of funny
it's the mitochondrion
mitochondrion is singular mitochondria
is plural
and every cell in your body has anywhere
from just a few to several thousand
mitochondria per cell
so the tissues that need more energy
they're going to obviously have more
mitochondria and those are primarily the
brain the heart and the liver
because the heart keeps pumping blood
all day long it never rests your brain
is is always always processing and your
liver is always trying to clean out and
and process all the foods that you eat
and
here's where it gets interesting I think
this is really funny it's one of these
quirks of nature
see if you think it's equally funny I'm
easily amused I guess
that mitochondria they're in our cells
but they're not really part of our
biology
they they have for for a long long time
they they have become part of our
biology but
they have their own DNA
so when you get your DNA from your mom
and your dad that does not include DNA
for mitochondria
you get 23 chromosomes from your mom and
23 from your dad and that makes 46 total
or 23 pairs but mitochondria is not in
there
so the mitochondria is a little
inclusion in the mother's egg
because every cell of your body has them
then but they don't participate in in
the conception part of combining DNA
so therefore you get all of your
mitochondria from your mother
and the interesting part is because of
this you can use this to trace lineage
because there's only a every time that
that the cell combines
from from the mother or father you have
a new completely unique human that never
existed before
but with mitochondria that doesn't
happen
there is no renewal of that DNA it's the
exact same except for occasional
mutations and that's only happened a few
times in the history of mankind
so there's only a handful it's like we
all belong to a mitochondrial Clan or
category
and if you trace this back we can
actually Trace every single human back
to one person
which they call mitochondrial eve
who lived in Africa somewhere around 190
000 to 200 000 years ago and she is the
ancestor of all humans on Earth today
they thank you thank you
so we don't all have the same father and
she was not the only female living at
the time but she was the only female
that have Offspring living today
and the only mitochondrial variations
since then have been from mutations so
that's how they can trace people back
and and sort of see where where people
come from and belong
so this mitochondria
it has its own circular DNA we have we
have cattle cross forms form dnas
23 of them the mitochondrial DNA is a
circular single chromosome
and
somewhere along probably hundreds of
millions of years ago there was a
bacterium
that migrated into a cell and somehow
helped that cell make energy so that the
two liked each other and stuck together
from that point on
and that's where where mitochondria live
and they make 95 of our energy so Life
as we know it could not exist if that
inclusion hadn't happened
so this becomes interesting also from a
health standpoint and aging standpoint
because it turns out this mitochondrial
DNA is not quite as sophisticated as as
our nuclear DNA
so humans live a really long time
because we have efficient repair
mechanisms for our DNA when something
goes wrong we can repair it and with and
because of that there's relatively few
flaws along the way and we age slowly
because of that
but in a manner of speaking our DNA our
mitochondria age faster than we do so
it's a function of of our aging and it's
a function of accelerated aging
because
it is much more susceptible to damage
first of all it only has rudimentary
capability of repair compared to our
nuclear DNA
but then the other factor is if you
remember we said that last time every
time that you make energy
with oxygen you also make a free radical
remember that it is an inevitables
byproduct of energy production
so inside the mitochondria is where all
the energy is made so the concentration
of free radicals in and around the
mitochondria is way way higher than
anywhere else
so not only are they poor at repairing
but they're exposed to a much much
higher level of free radicals than other
tissues
so because of this the mutation rate for
mitochondrial DNA is about 15 times
higher than nuclear DNA
and then on top of that it repairs worse
so
when these mitochondria get old and
don't function as well it's kind of like
a rusty engine
and
the ATP output goes down the energy
production goes down
but the
free radical output goes up so it's less
efficient so we get less out of it we
get less energy and more smoke if you
will
and Ros is reactive oxygen species
that's the other word for free radical
and
these two factors are associated with
accelerated aging and cancer
so we want to take care of our
mitochondria and provide them resources
so that they can sustain their energy
production better we have talked about
these some of these before but I'll
review them
CoQ10 is an enzyme it's used within the
membrane folds of the mitochondria to
make energy it's just part of that chain
that that creates it there are two forms
of CoQ10 one is called ubiquinone which
is inactive one is called ubiquinol
which is the activated
so after age 35 we lose two things we
lose the ability to make CoQ10
it starts actually declining from age 20
but after age 35 we also lose the
ability to convert the inactive to the
active so when we supplement it we
really want to make sure we get the
active form because that can be absorbed
and utilized as much as eight to ten
times better than the other form
another one we haven't talked about but
I think you guys are all using it is
acetyl L-Carnitine
this is something that occurs naturally
in the membranes of mitochondria and it
helps transport fatty fatty acids across
the membrane for burning so we have two
energy two primary energy sources it's
carbohydrates and fats but they have to
get across the membranes in order to be
available
and as the mitochondria gets damaged and
older then we can help them by providing
this
acetyl-l-carnitine so that they can get
the the
fuel into the cell better into the
mitochondria
and the acetyl group
that they add to the to the supplement
it helps the molecule cross the
blood-brain barrier and this is really
important because a lot of the
mitochondria were trying to help are in
the brain so we want to get this
substance across quickly and intact
so because of this
acetylcholine may have unique
neuroprotective
neuromodulary and neurotrophic
properties meaning neurotrophic is the
ability to grow new nerve cells new new
brain cells
and acetyl carnitine may also help with
memory function mitochondrial structure
and function inhibits age-related
oxidative damage and restore some key
enzymes as well
so it is most people who study aging put
it very close to the top of the list
and so do we
so the cartoon our bodies replace
millions of skin cells every day so how
come the new ones don't look any younger
than the old ones
and you guys are getting so
knowledgeable that you're it's not it's
just barely a joke anymore
you're gonna start start explaining that
pretty soon
so in summary
the mitochondria or
bacteria-like inclusions inside cells
that don't really belong to us they've
been there for a long long long time but
they're not part of our DNA they make
about 95 energy
and their DNA is less protected
and much more sensitive than our nuclear
DNA
whenever we make energy we create free
radicals and therefore these
mitochondria as they get damaged they
produce less energy and more free
radicals the engine starts smoking
this decline is associated with diseases
accelerated aging and and cancer
so what can we do we want to protect
ourselves and our mitochondria by number
one reducing stress that's what the sum
total of all these talks that we're
doing is about eat better move better
feel better and then we can take some
supplements
as follows
and one we want to add back what's
running low that's the CoQ10 or the
ubiquinol
we want to improve membrane transport
and that's acetyl L-Carnitine and we
want to help defend those mitochondria
against the free radical against
oxidative damage and the two top things
to take in addition to all other
antioxidants is an acetylcysteine NAC
which is a glutathione precursor and
undenatured way to also help boost
glutathione production
so that's the reason except for being
good food that's the reason you're
taking those the whey protein is for
glutathione and of course glutathione
helps protect every cell in the body but
along that the way they they predict the
mitochondria as well
so that is all we have thank you very
much for coming and now you know all
about mitochondria
isn't it though
