Detailed explanation-1: -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: -Aerobic respiration is much more efficient due to the high production of ATP. This high production occurs due to the complete breakdown of glucose into CO2 and Energy (ATP).

Detailed explanation-3: -Aerobic respiration is much more efficient than anaerobic respiration. One molecule of glucose can generate up to 38 molecules of ATP if aerobic respiration is used. In contrast, only 2 molecules of ATP are generated in anaerobic respiration.

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.
