Answer 1

For every glucose molecule undergoing glycolysis, six NADH + H+ are produced during the citric acid cycle, as a result of two turns of the cycle per glucose molecule.

Step-by-step explanation:

For each molecule of glucose that goes through glycolysis, six NADH + H+ are produced in the citric acid cycle. This result stems from the fact that one molecule of glucose yields two molecules of acetyl-CoA, each of which enters the citric acid cycle.

For every turn of the citric acid cycle, three molecules of NADH are produced. Therefore, since we have two turns of the cycle per glucose molecule, a total of six NADH + H+ are formed.
