So in this video, let's do an aerobic respiration summary, right. So here we have our starting molecule, we have carbon dioxide A TP fa DH two N A DH. And then we have our and molecule. Now, lipids proteins or carbohydrates, we'll talk about in greater detail later on. So we'll keep this part great out. Next, we have crept cycle which is the citric acid cycle and oxidative phosphorylation. Now remember the electron transport chain is part of this oxidative phosphorylation. So just think of it as going from complex one all the way to complex five for this section. Now remember that crep cycle is stage three of our food metabolism and we can think of etc and oxidative phosphorylation at stage four together, they make the common metabolic pathway. Now, at this point, we know that the starting material for our crept cycle is two of acetyl coa we know that the amount of CO2 we make is four A TP is two, FA DH two is also two N A DH six and our end molecule would be oxalacetate. Now, here we have oxidative phosphorylation. We're going to basically take the FA DH two and the N A DH that we made in crep cycle, they're being shuttled off from stage three to stage four of food metabolism. So this would be six and this would be two. Now, the amount of CO2 that's produced is zero. This happens in crept cycle, not in oxidative phosphorylation or etc A TP. Remember we said theoretically, we can make 18 A TP molecules fa DH two. Well, it gets oxidized back into F AD. So it's zero, being more being made N A DH, more of it isn't being made. It's just coming in, dropping off its electrons at complex one. So there are no more N A DH is being created in the etc or oxidated phosphorylation. Finally, our end molecule in oxidated phosphor population, the final electronic cept is 02 and that helps to make water. All we do now is we add up our totals. So we'd say that we'd have a total of four carbon dioxides. We'd have a total of 20 A TP. We'd have two FA DH two and six N A DH is being created if we're looking at the common metabolic pathway. So stages three and four of food metabolism. So keep these numbers in mind or asked about the summary of aerobic respiration.

What are the total A TP molecules produced by N A DH from the citric acid cycle? Now, remember two rounds of the citric acid cycle creates a total of six N ad agents. I remember that on average, we're making 2.5 A TP per N A DH. So here we just do six times 2.5. When you punch that into your calculator, you should get back 15 A TP. So here we say that the total amount of A TP molecules produced by N A DH from the citric acid cycle. And remember we're talking about two rounds of it because there's two acetyl coa involved. It would be 15 A TP molecules. So here our answer would be option C.
