Accepted Answer

Hi everyone. That's a good. The next problem it says which of the following options correctly includes all the products of glycol icis. So let's kind of walk through a basic outline of like Alexis so we can recall which products are being produced at different points. We of course start with glucose and it's gonna end up being converted to fructose 1 6 this phosphate consuming two molecules of A. T. P. In the process. Since it got two phosphate groups added to it, That is eventually going to become two molecules of Glycerol to hide three phosphate. It's now two molecules because fructose is a six carbon molecule and glycerol three phosphate is a three carbon molecule. So we've now got two of these and they are eventually gonna end up as piru bait which is also a three carbon molecule. You haven't put off any carbons in the process. And you do end up when you see we have two phosphate groups here that are going to be removed. One of the intermediate products has you've added a phosphate group to a three carbon molecule. So you did have another phosphate group added earlier along the way. So you need you have two phosphate groups were moved from each molecule. So in that we're going to see the production of two molecules of a T. P per molecule here. So the total well before for each molecule glucose and then in this process you also have any D plus accepting electrons. I'm becoming N A. D. H. So when we look at our products here we have peru we have N. A. D. H and we have a T. P. There was a T P consumed up here, but it was just two molecules of a teepee. Down here. We have four molecules of ATP produced. So when we look at our answer choices, we see that choice D is tire of 8 80 P and N A. D. H, which are products of glycol Asus. We can just briefly look at our other answer choices. We have Choice A which is alcohol, carbon dioxide and N A D. N A D. Is consumed not produced and neither alcohol nor carbon dioxide are products of psychosis. So, cross that off choice B is lactic acid in N A D. Again, en A. D. Is consumed and lactic acid is not one of our products. And finally, Choice C. A T. P, water and carbon dioxide. Um we didn't lose any carbons along the way. So we're not producing any carbon dioxide. So Choice C is not our answer. So, again, which option correctly includes all the products of psychosis. Choice D P A T P and N A D. H.
