Question

Which of the following statements is incorrect

• A. Oxidation-reduction reactions produce proton gradient in respiration
• B. During aerobic respiration, role of oxygen is limited to the terminal stage
• C. 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
• D. ATP is synthesized through complex V

Answer 1

The Correct Option is C

In the electron transport chain (ETC), the exact number of ATP molecules generated per molecule of NADH+H⁺ and FADH₂ varies depending on the specific conditions and organism. In general, each molecule of NADH+H⁺ produces approximately 3 ATP molecules, while each molecule of FADH₂ typically produces about 2 ATP molecules. So, the statement as presented is not entirely accurate, and it varies based on the specific details of the system.

So, the correct option is (C): 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
