Detailed explanation-1: -Two molecules of acetyl-CoA are produced from each glucose molecule so two turns of the Krebs cycle are required which yields four CO2, six NADH, two FADH2 and two ATPs.
Detailed explanation-2: -In this process, two molecules of ADP are phosphorylated to ATP, and a single molecule of NAD is reduced to NADH. The net result of this from a single molecule of glucose is two molecules of pyruvate, two molecules of ATP, and two molecules of NADH.
Detailed explanation-3: -The net energy output for one glucose molecule from glycolysis through the Krebs cycle is: 4 ATP, 10 NADH + H+, and 2 FADH2.
Detailed explanation-4: -Products and Functions of the Krebs Cycle For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced.
Detailed explanation-5: -Step 6 is the first step in which NAD+ is reduced to form NADH. Two NADH molecules are formed for every one glucose molecule.
