Detailed explanation-1: -For every glucose molecule that enters glycolysis, this creates 2 ATP and 6 NADH. The majority of the energy is in the electron transport chain ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle).
Detailed explanation-2: -How much ATP is produced in all three stages combined? Glycolysis produces 2 ATP molecules, and the Krebs cycle produces 2 more. Electron transport from the molecules of NADH and FADH2 made from glycolysis, the transformation of pyruvate, and the Krebs cycle creates as many as 32 more ATP molecules.
Detailed explanation-3: -The NADH and FADH generated during the Krebs cycle fuels the electron transport chain which drives this process, ultimately producing 38 molecules of ATP.
Detailed explanation-4: -The Krebs cycle is the second phase in cellular respiration. It occurs in the mitochondria in the cell. The number of ATP molecules produced in the Krebs cycle is 2.
Detailed explanation-5: -In glycolysis, there is a net gain of 2 ATPs. 2 ATPs are produced in the TCA cycle per glucose molecule (2 acetyl CoA).
