Explanation:
Detailed explanation-1: -During the pyruvate oxidation 2 NADHs are produced. During Krebs cycle 6 NADHs are formed. So, total 10 NADHs are formed during complete oxidation of glucose.
Detailed explanation-2: -Our correct answer is three molecules of reduced NAD are produced.
Detailed explanation-3: -To answer our question, two molecules of reduced NAD are produced when one molecule of glucose undergoes glycolysis.
Detailed explanation-4: -All told, the Krebs cycle forms (per two molecules of pyruvic acid) two ATP molecules, ten NADH molecules, and two FADH2 molecules.
Detailed explanation-5: -The net energy output for one glucose molecule from glycolysis through the Krebs cycle is: 4 ATP, 10 NADH + H+, and 2 FADH2.
