So we already know that if we start off with a glucose

molecule, which is a 6-carbon molecule, that this

様態の副詞

essentially gets split in half by glycolysis and we end up 2

So glycolysis literally splits this in half.

We end up with two pyruvates or pyruvic acids.

You saw it in the past. And you could look up their

chemical structures on the internet or on Wikipedia and

Is that it was lysed, it was cut in half.

And this happened in the absence of oxygen.

It can happen in the presence or in the absence of oxygen.

And I always say the net there, because remember, it

used two ATPs in that investment stage, and then it

So on a net basis, it generated four, used two, it

And just so you can visualize this a little bit better, let

It has its DNA and its chromatin form all spread

And there's a reason why people call it the power

I'll do more detail on the structure of a mitochondria,

maybe later in this video or maybe I'll do a

And then all of this fluid, this space out here that's

between the organelles-- and the organelles, you kind of

view them as parts of the cell that do specific things.

So this-- so between all of the organelles you have this

Now we all know-- in the overview video-- we know what

The Krebs cycle, or the citric acid cycle.

And that actually takes place in the inner membrane, or I

should say the inner space of these mitochondria.

If I have just one inner membrane we call it a crista.

This little convoluted inner membrane, let

Because it's divided by these two membranes.

This compartment right here is called the outer compartment.

This whole thing right there, that's the outer compartment.

And then this inner compartment in here, is called

Now you have these pyruvates, they're not quite just ready

for the Krebs cycle, but I guess-- well that's a good

And I'll just focus on one of these pyruvates.

We just have to remember that the pyruvate, that this

happens twice for every molecule of glucose.

And essentially what it does is it cleaves one of these

And so you end up with a 2-carbon compound.

You don't have just two carbons, but its backbone of

And if these names are confusing, because what is
