Glycolysis means we're going to be breaking up glucose.

And so essentially glucose concentration will go up high here, and then if we make this porous to glucose so glucose can go through, then glucose will eventually, if this gets high enough, it'll just go down its concentration gradient eventually into the blood.

It lyses the glucose.

But the first step of cellular respiration is glycolysis breaking up of glucose.

So the whole point is really to go from glucose, from one mole of glucose

The first stage is glycolysis, where you're just literally splitting the glucose into two.

Glucose has been split.

Over here we have our glucose.

Maybe glucose will bond here.

It's taking glucose for the ride.

Which literally means breaking up glucose.

Glucose was our starting point.

So if you had one mole of glucose let me write that, that's your glucose right there and then to that one mole of glucose, if you had six moles of molecular oxygen running around the cell, then and this is kind of a gross simplification for cellular respiration.

The liver helps regulate glucose levels by reducing its secretion of glucose in the presence of insulin.

The first stage is called glycolysis.

So, glycolysis anaerobic.

It is a type of glucose clamp technique.

It's more likely too much glucose blood sugar.

It's taking so much glucose from my bloodstream.

So cellular respiration, for every mole of a glucose,

I'll just do the example of glucose.

So that's your glucose right there.

Let me show you what glucose actually looks like.

That's what glycolysis does, right there.

They're saying, hey, we have 25 grams of glucose.

But the process of glycolysis, you're essentially just taking

We started off with 12 hydrogens in glucose.

The brain is a bit of a hog when it comes to using glucose.

Or if we want to be specific, from glucose.

So that's what glucose actually looks like.

That little glucose molecule then helps to build bigger and better carbohydrates

But why do we have to turn that glucose into ATP?

So you start off with glucose in the investment phase.

Glucose got split into two of these guys.

The hospital put him on a water drip for three days.

How much oxygen is required to completely react with that glucose?

I'll do a whole video on glycolysis in the future.

But insulin is vital, without insulin you have diabetes. and without insulin you don't transport glucose into muscle, and remove glucose from the bloodstream normally.

So glycolysis, or really cellular respiration, it starts off with glucose.

Because the glucose has been split into two of these molecules.

And actually, for every molecule of glucose you have six carbons.

So what we have are symporters over here, just like we had with glucose, but in this case, sodium wants to enter just as the case with glucose, but here we're trying to transport chlorine and potassium ions.

But the important thing to remember is cellular respiration all it is is taking glucose and kind of repackaging the energy in glucose and repackaging it in the form of, your textbooks will tell you, 38 ATPs.

Any excess glucose stimulated the pancreas to release insulin, which transported glucose into peripheral fat tissue, and which also caused the liver to store glucose as glycogen (liver starch).

A mathematical derivation known as the HOMAI, calculated from the fasting values in glucose and insulin concentrations, allows a direct and moderately accurate measure of insulin sensitivity (glucose level x insulin level 22.5).
