Glycolysis breaks glucose down into dihydroxyacetone phosphate and glyceraldehyde-3-phosphate, but only glyceraldehyde-3-phosphate can be converted to pyruvate. Why is it that we can still obtain two molecules of pyruvate from a glucose molecule despite not being able to make pyruvate from dihydroxyacetone phosphate?
Homework Answers
We obtain two molecules of pyruvate because the dihydroxyacetone phosphate formed by the breakdown of fructose 1,6 bisphosphate (catalyzed by aldolase) is converted into glyceraldehyde-3-phosphate in a reaction catalyzed by the triosephosphate isomerase. So one molecule of glyceraldehyde-3-phosphate is formed by aldolase and one molecule is formed by conversion of dihydroxyacetone phosphate into glyceraldehyde-3-phosphate. So there are total 2 molecules of glyceraldehyde-3-phosphate. Since one molecule of glyceraldehyde-3-phosphate produces 1 pyruvate, 2 molecules of pyruvate are formed by two molecules of glyceraldehyde-3-phosphate.

Which will produce more ATP: i). Three molecules of glucose that are metabolized by glycolysis to yield pyruvate orii). Three molecules of glucose that enter the Pentose Phosphate pathway and are converted to two molecules of fructose-6-phosphate and one molecule of glyceraldehyde-3-phosphate, which can then enter glycolysis. Explain your metabolic calculations/logic. NOTE: Do not consider ATP equivalents from NADH or NADPH in your answer.

During EMP glycolysis, 1 molecule of glucose is broken down into two molecules of pyruvate and 2 molecules of NADH are produced. During fermentation, 1 molecule of pyruvate is reduced. During this process, one molecule of NADH is oxidized. If 34 molecules of glucose are broken down during glycolysis, and all the resultant molecules of pyruvate are reduced by fermentation, how many molecules of NADH will remain?
