Question

Compare and contrast substrate-level phosphorylation and oxidative phosphorylation.

Accepted Answer

hi everyone. Let's look at this next problem. It says given the following descriptions identify which are the features of oxidative and substrate level phosphor relation. And were given four statements. And then our answer choices involve us identifying which of them is true. So let's recall uh the difference between substrate level phosphor relation and oxidative phosphor relation. So substrate substrate level phosphor relation is when A T. P. Is formed by transfer of a phosphate group from another molecule. And this occurs in respiration in the Krebs cycle and and like Alexis. And it produces 6 80 molecules of ATP. In the complete oxidation of one molecule of glucose. Oxidative phosphor elation is when A T. P. Is produced when electrons are transferred from electron electron carriers of an A. D. H And FATH two through the electron transport chain. And then that energy used to generate A T. P. In the process of keamy osmosis. And this process produces a lot more ATP it ends up producing 32 molecules of AT. So let's look at our statements and see which of them is true. And then we can find our correct answer choice here. So m statement M says substrate level phosphor relation produces more 80 P. Well, this is false Oxidative phosphor relation produces more of A T. P. So that's a false statement statement and says oxidative phosphor relation produces less energy. This is also false. We see that oxidative phosphor relation produces more E. T. P. And therefore more energy and statement, Oh says a T. P is formed during glycol icis through substrate level phosphor relation. Well, that is true substrate level phosphor relation includes the processes that take place in glycol icis. And finally, statement P says the exact mechanism of a teepee formation and oxidative phosphor relation is keamy osmosis and that is true. So that's when we have the protons that are pumped across the membrane against the concentration gradient. Using the energy from the electrons transferred through the electron transport chain. Those protons flowed down the concentration gradient through a TP keenness and generate a molecule of ADP through the process of keamy osmosis. So we've got two true statements O and P. So let's look at our answer choices and we see the choice B says O N. P. So that is our answer. Because we have just those true statements. O. A T. P. Is formed during like analysis through substrate level phosphor relation and P. The exact mechanism of a teepee formation and oxidative phosphor relation is keamy osmosis. See you in the next video
