How 36 Atp Is Produced?
Cellular Respiration Produces 36 Total Atp per Molecule of Glucose Across Three Stages. Breaking the Bonds Between Carbons in the Glucose Molecule Releases...

Considering this, where do the 36 ATP come from?
First off, let's divide the 36 ATP into three parts — ATP that comes from glycolysis, and ATP that comes from the Krebs Cycle and the Electron Transport Chain. Glycolysis is the process that breaks down the 6-carbon glucose into 3-carbon pyruvate, which is a substrate for the link reaction.
Subsequently, question is, how much ATP is produced in each stage? Glycolysis produces 2 ATP molecules, and the Krebs cycle produces 2 more. Electron transport begins with several molecules of NADH and FADH2 from the Krebs cycle and transfers their energy into as many as 34 more ATP molecules.
Subsequently, question is, how are 38 ATP produced?
Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. 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).
Does aerobic respiration produce 36 or 38 ATP?
According to some of newer sources the ATP yield during aerobic respiration is not 36–38, but only about 30–32 ATP molecules / 1 molecule of glucose , because: ATP : NADH+H+ and ATP : FADH2 ratios during the oxidative phosphorylation appear to be not 3 and 2, but 2.5 and 1.5 respectively.
