Detailed explanation-1: -2 ATPs are produced in one Krebs Cycle. For complete oxidation of a glucose molecule, the Krebs cycle yields 4 CO2, 6NADH, 2 FADH2 and 2 ATPs.
Detailed explanation-2: -NADH and carbon dioxide are products of the Krebs Cycle.
Detailed explanation-3: -Krebs cycle produces the following: Two molecules of carbon dioxide are given off. One molecule of ATP is formed.
Detailed explanation-4: -In the Krebs cycle, two ATP, six NADH +H+, and two FADH2 were produced. A net of four ATPs was produced from glycolysis through the Krebs cycle. More ATP will be produced from reduced coenzymes in the mitochondria during the electron transport chain and oxidative phosphorylation.
Detailed explanation-5: -In the eighth or last step, malate is dehydrogenated so as to form Oxaloacetate. This combines with another molecule of acetyl CoA resulting at the beginning of a new cycle. Thus, one acetyl CoA forms one ATP molecule. Hence, the two will form 2 ATP molecules in one cycle of the Krebs cycle.
