Detailed explanation-1: -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. Therefore, a total of up to 36 molecules of ATP can be made from just one molecule of glucose in the process of cellular respiration.
Detailed explanation-2: -Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
Detailed explanation-3: -It has been known for many years that oxidation of glucose does not yield 38 ATP. Estimates on the yield vary, but there is some consensus that the yield is approximately 29−32 ATP molecules per glucose molecule.
