A single molecule of glucose requires _____ "turn(s)" through the citric acid cycle for its chemical energy to be completely harvested.

Question

Quizplus · Accepted Answer

A single molecule of glucose enters the citric acid cycle as two molecules of acetyl-CoA, which then goes through a series of reactions that generate energy in the form of ATP, NADH, and FADH2. It takes two turns through the citric acid cycle (one turn for each acetyl-CoA molecule) to completely harvest the energy from a molecule of glucose. Therefore, the answer is B - 2 turns.
