Detailed explanation-1: -While Krebs’ cycle produces two GTP molecules. These two GTP molecules are therefore turned into two ATP molecules. Electron Transport System generates 32 or 34 ATP molecules and is the cell’s main source of energy. Thus, the electron transport system produces the most ATP in cellular respiration.

Detailed explanation-2: -Answer and Explanation: The process that creates the most ATP per glucose molecule is aerobic cellular respiration. During this process one glucose molecule is used with oxygen to create 32-34 ATP molecules, carbon dioxide and water.

Detailed explanation-3: -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-4: -The majority of ATP synthesis occurs in cellular respiration within the mitochondrial matrix: generating approximately thirty-two ATP molecules per molecule of glucose that is oxidized.
