Nelson!

Roger that.

And then they enter into what's called the Krebs cycle.

The Krebs cycle, or the citric acid cycle.

After being done with glycolysis and the Krebs

But it's really a preparation step for the Krebs cycle.

This long talked about Krebs cycle.

Then we're ready to enter the Krebs cycle.

After a brief illness, Krebs died on 22 November 1981 in Oxford.

Krebs is a city in Pittsburg County, Oklahoma, United States.

But then you move over to the Krebs cycle, which is aerobic.

Everything in the Krebs cycle is an enzyme catalyzed reaction.

Glycolysis, the preparatory stage and the Krebs or citric acid cycle.

So we have this kind of preparation step for the Krebs Cycle.

But the reality is, six from the Krebs cycle two from the preparatory stage.

And then you go to the Krebs cycle, there's a little bit of setup involved here.

Krebs cycle or the citric acid cycle gets credit for this step.

So they'll say eight NADHs get produced from the Krebs cycle.

And then the citric acid is oxidized through the Krebs cycle right there.

Now, sometimes in a lot of books these two NADHs, or per turn of the Krebs cycle, or per pyruvate this one NADH, they'll give credit to the Krebs cycle for that.

And then when we look at this side, the formal Krebs cycle, what do we get?

But it's normally viewed to be after glycolysis and the Krebs cycle.

Now, in the citric acid cycle, or in the Krebs cycle, well first we have our pyruvate oxidation.

But the interesting thing is that the Krebs cycle is the entry point for these other catabolic mechanisms.

And where a lot of our NADH, or really all of our NADH, is sitting.

Then those byproducts are split even more in the Krebs cycle, directly producing two ATPs.

Edwin Gerhard Krebs (June 6, 1918 December 21, 2009) was an American biochemist.

You'll have some NAD plus, which you can then go and use back in the Krebs Cycle and in glycolysis.

And then, and this is kind of the interesting point, there's another process that you can say happens after the Krebs cycle.

So, so far, if you include the preparatory step, we've had four NADHs formed, three directly from the Krebs cycle.

Now once you have this 2 carbon chain, acetyl Co A right here. you are ready to jump into the Krebs cycle.

The Krebs cycle is really formally this part where you start with acetyl CoA, you merge it with oxaloacetic acid.

And then most especially introductory textbooks will give the Krebs cycle credit for this pyruvate oxidation, but that's really a preparatory stage.

Now you have these pyruvates, they're not quite just ready for the Krebs cycle, but I guess well that's a good intro into how do you make them ready for the Krebs cycle?

But the big picture here is acetyl CoA is the general catabolic intermediary that can then enter the Krebs cycle and generate ATP regardless of whether our fuel is carbohydrates, sugars, proteins or fats.

You get two NADHs and you get two pyruvates, which are going to be re engineered into acetyl CoAs that are going to be the raw materials for the Krebs cycle.

If we have oxygen we can move to the Krebs cycle, get our two ATPs, and then go on to the electron transport chain and produce 34 ATPs, which is really the bulk of what happens in respiration.

Cripps proposed giving some provinces what was dubbed the local option to remain outside of an Indian central government either for a period of time or permanently, to become dominions on their own or be part of another confederation.
