Detailed explanation-1: -The metabolic cycle that provides the highest net ATP per glucose molecule is oxidative phosphorylation. In the glycolysis stage, 2ATP, 2NADPH, and 2 pyruvates are produced for each molecule of glucose.
Detailed explanation-2: -The mitochondrion performs most cellular oxidations and produces the bulk of the animal cell’s ATP. The mitochondrial matrix contains a large variety of enzymes, including those that convert pyruvate and fatty acids to acetyl CoA and those that oxidize this acetyl CoA to CO2through the citric acid cycle.
Detailed explanation-3: -Oxidative phosphorylation or the electron transport chain produces 28 ATP for every one glucose in aerobic cellular respiration.
Detailed explanation-4: -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.
