In terms of high-energy molecules, what is the net output for one molecule of glucose undergoing glycolysis?

Question

Accepted Answer

Welcome back everybody. Our next question says, give the net output of high energy molecules for five molecules of galactose in glycolysis A five A TP and five N A DH B 10 A TP and five N A DH C 10 A TP and 10 A DH or D five A TP and 2.5 N A DH. So as our problem reminds us, the high energy molecules produced by glycolysis are not just A TP but N A DH since N A DH is an electron carrier and therefore can be used to donate electrons. So what is the yield in glycolysis for galactose? Well, galactose like glucose is a hexose. So it can enter the glycolytic pathway to be metabolized similarly to glucose. So we can just think of the normal process of glycolysis with glucose as the starting molecule because we'll get the same results in terms of high energy molecules produced. So let's recall what that production is, which would be for one molecule of galactus or glucose. Our energy, our yield of high energy molecules will be a net yield. We'll say net two A TP molecules recall that four A TP molecules will be produced, but two A TP molecules will be consumed. So our net yield is two A TP plus two N A DH molecules. Now we want the yield for five molecules. So we simply multiply both of these by five and our net yield for five molecules will therefore be choice C 10 A TP and 1088 N A DH. So that was a pretty straightforward problem. Our answers choice C there, we will see you in the next video.
