Accepted Answer

Hi everyone. Let's look at our next problem. It says in the mitochondria in the processing of ADP to produce a. T. P. Is dependent on that. And our answer possibilities are oxidative phosphor relation, colossus citric acid cycle, Krebs cycle. Well the first thing I want to do is we look at our answer choices is to notice choice, C citric acid cycle and choice. The Krebs cycle are the same thing. Those are two names for the same process. So if I'm on a test and time is of the essence I'm gonna go ahead and rule them both out. Um They can't they're the same thing and they can't both be the answer. Since we don't have an option for multiple correct answers. So I'm gonna know right away that that can't be our answer. Um We'll go a little more thoroughly into this just in the interest of explaining things. But again if I'm on a test I'm going to rule out C. And D. Right away. So let's look again at our question And I'm looking for the processing of ADP to produce a T. P. Well what where does that reaction occur? How does that reaction occur through the action of the Enzyme 80 P. Keens. And as we recall from our content videos, A T. P keenness, you have. Protons flowing down an electrochemical gradient from an area of greater concentration to an area of lesser concentration that is energetically favorable. They flow through the A. T. P. Kindness. The energy of that favorable movement is used in the catalysis of the reaction that adds a phosphate group to A. D. P. To produce a T. P. Which is what we're asking for the processing of ADP to produce a. T. P. So that reaction occurs by the action of a teepee canes As protons slowed down an electrochemical gradients. This process is oxidative phosphor relation which is choice A. So that is going to be our answer phosphor relation. Obviously it's the addition of a phosphate group and oxidative because it depends on those oxidative reactions occurring in the mitochondria which are those redox reactions of electrons moving down the electron transport chain. Um electrons donated by electron donors at a high energy level. They move through the electron transport chain, um losing energy with each transfer until they're accepted by oxygen as the final electronic sector. And as they give off their energy moving down the electron transport chain. So those are the oxidation reactions recurring. That energy is used to pump protons against an electrochemical gradient and that is what gives them the potential energy that will then be utilized in oxidative phosphor relation. So oxidative phosphor relation is that process to process A D. P into a teepee. So let's just look briefly at our other answer choices to understand why they are not correct glycol icis is the reaction that extracts energy from the breakdown of glucose into two molecules of the three carbon piru bait. So that does generate energy but it's not what the processing of ADP into a teepee is dependent on its rather dependent on that oxidative bus for relations. So that's not our answer. And then as we said, that citric acid cycle or Krebs cycle, two names for the same thing are when you harness the chemical energy of the compound of Seattle Co. A. PirU. From electrolysis is converted into acetyl Co. A. By generating and A. D. H. And F A. D. H. Two which have high energy electrons that can then donate electrons electron transport chain used to produce a T. P. So these processes can generate a little bit of a TP directly. Um but generate the most amount of a teepee by producing those N A D. H and F A T. H. Two. But the actual reaction of adding phosphate to ADP to produce A D. P. Is dependent on the oxidative phosphor relation. Process choice. A. See you in the next video
