Explanation:
Detailed explanation-1: -In one turn of the Krebs cycle, 3 molecules of NADH are produced. For complete oxidation of a glucose molecule, Krebs cycle yields 4 CO2, 6NADH, 2 FADH2 and 2 ATPs.
Detailed explanation-2: -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-3: -Oxaloacetate is regenerated at the end of the cycle. For each glucose that enters glycolysis, products of the citric acid cycle are 2 ATP, 6 NADH, and 2 FADH2.
