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: -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.

Detailed explanation-3: -The correct answer is option c. Oxidative phosphorylation, which occurs in the electron transport chain stage of cellular respiration, produces the most ATP molecules.

Detailed explanation-4: -During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
