Which of the following statements is incorrect ? (1) During aerobic respiration, role of oxygen is limited to the terminal stage. (2) In ETC (Electron Transport Chain), one molecule of NADH+H+ gives rise to 2 ATP molecules, and one FADH2 gives rise to 3 ATP molecules. (3) ATP is synthesized through complex V. (4) Oxidation-reduction reactions produce proton gradient in respiration.
Option 2) In ETC of respiration, oxidation of one molecule of NADH+H+gives rise 3 ATP and FADH2 produces 2 ATP.
