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: -Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.
Detailed explanation-3: -Without oxygen, some human cells must use fermentation to produce ATP, and this process produces only two molecules of ATP per molecule of glucose. Although fermentation produces less ATP, it has the advantage of doing so very quickly.
Detailed explanation-4: -In aerobic respiration, the full oxidation of one glucose molecule can theoretically yield 38 ATP molecules.
Detailed explanation-5: -It is a part of cellular respiration. Here, energy to drive phosphorylation comes from oxidation-reduction reactions. More items
