During glycolysis no FADH2 molecules are produced.
While during Tricarboxylic Acid Cycle (TCA), when succinate is changed to fumerate, one molecule of FADH2 is produced by the reduction of FAD+ to FADH2 from one molecule of pyruvate.
As we know, during glycolysis two molecules of pyruvate are formed,so each pyruvate,when it undergoes TCA produces one molecule of FADH2 .
So,a total of two FADH2 molecules are produced during TCA from one molecule of glucose.
Hence, option (B) is the correct answer for this question.

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?

In a liver cell, if a single molecule of glucose undergoes glycolysis
In a liver cell, if a single molecule of glucose undergoes glycolysis, and the citrate cycle completes along with the electron transport chain, how many net ATP molecules are produced based on the chemical potential energy contained in the glucose substrate? Assume that no other pathways were involved.

a. The metabolism of glucose by glycolysis to acetyl-coenzyme A, followed by the TCA cycle, releases CO2 molecules by oxidative decarboxylation reactions. Write down the oxidative decarboxylation reactions that result in CO2 production. Name the enzyme involved in each reaction and give the names and complete structures of all reactants and products. Only abbreviated names of enzyme cofactors are required. (b) From the steps drawn in part (a) above, how many total ATP molecules would be produced from oxidative phosphorylation?
