Detailed explanation-1: -For complete oxidation of a glucose molecule, the Krebs cycle yields 4 CO2, 6NADH, 2 FADH2 and 2 ATPs.
Detailed explanation-2: -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-3: -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. Each glucose molecule produces two molecules of acetyl CoA, enough for two cycles.
Detailed explanation-4: -Overview of the Krebs or citric acid cycle, which is a series of reactions that takes in acetyl CoA and produces carbon dioxide, NADH, FADH2, and ATP or GTP.
Detailed explanation-5: -Thus, 1 glucose molecule is responsible for the release of 4 CO2 molecules during Krebs cycle.
