Recall that glycolysis is the metabolic pathway that converts one molecule of glucose into two molecules of pyruvate.
Understand that during glycolysis, specific enzymatic steps involve the reduction of NAD+ to NADH, which is a key electron carrier.
Identify the step in glycolysis where NAD+ is reduced: this occurs during the conversion of glyceraldehyde-3-phosphate (G3P) to 1,3-bisphosphoglycerate, catalyzed by glyceraldehyde-3-phosphate dehydrogenase.
Since one glucose molecule produces two molecules of G3P, and each G3P produces one NADH, multiply the number of NADH produced per G3P by 2 to account for both molecules.
Conclude that the total NADH produced per glucose molecule during glycolysis is the product of NADH per G3P times 2.
