a. the transfer of from intermediate substrates to ADP
b. the movement of H+ across a membrane down its concentration gradient
c. the splitting of glucose into two molecules of pyruvate
d. electrons moving through the electron transport chain

Accepted Answer

Hi everyone. Let's look at our next problem. It says which of the following processes provides energy in the form of a TP to nearly all living organisms. So let's look through our answer choices here and choice A. Says like hollis and hollis is the correct answer here. Glycol isIS is of course we recall that process by which um glucose is broken down into smaller molecule releasing energy and making a teepee. And hollis is found in nearly all living organisms is thought to be a very ancient process as a result. Um And it's anaerobic does not require does not require oxygen. So it was able to be used even in very ancient times when there was no oxygen in earth's atmosphere. But let's look at our other answer choices here. Um Oxidative phosphor relation only found in cells with mitochondria. So of course that leads out um All of your pro carry outs leaves out your plant cells. So definitely not found in nearly all living organisms. Choice C. Is alcoholic fermentation, alcohol, alcoholic fermentation takes place in yeast. So again not something that's in all living organisms. So not our answer. And finally, lactic acid fermentation choice D. That's just found in some bacteria and some animal cells particular particularly muscle cells as an alternative to the slower aerobic respiration, allowing energy to be generated even when the oxygen supply isn't keeping up. But again not something that's found in nearly all living organisms. So Choice D. Is not our answer. So which of the following processes provides energy in the form of a TP to nearly all living organisms. Choice A glycol icis. See you in the next video.
