Detailed explanation-1: -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-2: -The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS). The inner mitochondrial membrane holds the ATPase enzyme and the complexes for ETS.
Detailed explanation-3: -In aerobic conditions, pyruvate enters the citric acid cycle and undergoes oxidative phosphorylation leading to the net production of 32 ATP molecules. In anaerobic conditions, pyruvate converts to lactate through anaerobic glycolysis.
Detailed explanation-4: -Answer and Explanation: Cellular respiration harvests the most chemical energy from chemiosmotic phosphorylation. Chemiosmotic phosphorylation is the process through which an osmotic gradient is used to supply the energy which is needed to phosphorylate ATP.
