Accepted Answer

Hi, everybody. Welcome back. Our next question says in cellular respiration, what broader process does the production of A TP from an electron transport chain belong to a glycolysis. B oxidative phosphorylation, see crib cycle or D citric acid cycle. Well, to remember what this process is called, we want to think about the fact that we have electron transfers occurring in that electron transport chain. So it's a series of redox reactions and we have the ultimate production of A TP. So we're going to have phosphorylation of AD P occurring. So that can help us remember that this whole process is called choice B oxidative phosphorylation. So that's that process where you have your um N AD H and FA DH two transferring their electrons to the electron transport chain. And then the energy released in the electron transport chain. As those electrons go from protein to protein is used to establish a proton gradient that energy powers the pumping of protons up the gradient across the inner mitochondrial membrane. And then at the end, the prose protons going down the gradient through the A TP synthese protein power, the synthesis of A TP. So that's the sort of summary of that whole process. And we now just to be thorough, look at our other answer choices, choice, a glycolysis. This is at the beginning of this entire process, it's not part of respiration itself. It's the process by which glucose is converted to pyruvate. So from a six carbon molecule to three or excuse me, 23 carbon molecules and that generates two molecules of A TP and two molecules of N DH. That as we can see will be also used later as an electron carrier. But it's not the part where that produces a TP from an electron transport chain. The A TP produced in glycolysis is produced by substrate level phosphorylation. So choice A isn't the right answer. And then choices C and D creb cycle and citric acid cycle are the same name or two different names, excuse me for the same process. So it's the same process. And in this process, you start with acetyl coa which is produced from pu eight and it goes through this cycle which is called either the crab cycle or the citric acid cycle. And the end result is CO2. So the, the glucose from that entered glycolysis has now been broken completely down into carbon dioxide. And then it generates two A TP molecules, three N A DH molecules and two fa DH two molecules. And then those molecules of N A DH and FA DH two will then go on to the electron transport chain as we saw before. But that's not the process that is producing a TP from an electron transport chain. So C and D like glycolysis take place before the electron transport chain. So they produce some A TP but not by use of an electron transport chain. So the particular part of this larger process of cellular respiration that involves the production of a TP from an electron transport chain. His choice B oxidative phosphorylation. See you in the next video.
