Question

In the citric acid cycle, for each pyruvate that enters the cycle, 1 ATP, 3 NADH, and 1 FADH2 are produced. For each glucose molecule that enters glycolysis, how many ATP, NADH, and FADH2 are produced in the citric acid cycle

Answer 1

two ATP, six NADH and two FADH2

Step-by-step explanation:

The citric acid cycle refers to a series of metabolic reactions that take place in aerobic organisms. These reactions are used to oxidate fuel molecules (such as, for example, glucose) in order to release energy. In the citric acid cycle, the pyruvate generated from one glucose molecule is oxidized to produce acetyl CoA, where a carboxylate group is removed to form CO2. The products of this reaction are one ATP, three NADH, and one FADH2. Since two acetyl-CoA molecules for every glucose molecule, these products need to be multiplied by two to obtain the per-glucose yield (i.e., two ATP, six NADH and two FADH2).
