Question

Which of the following statements is incorrect?

• A. During aerobic respiration, role of oxygen is limited to the terminal stage.
• B. In ETC (Electron Transport Chain), one molecule of $NADH + H^{+}$gives rise to 2 ATP molecules, and one $FADH _{2}$ gives rise to $3$ ATP molecules.
• C. ATP is synthesized through complex $V$.
• D. Oxidation-reduction reactions produce proton gradient in respiration.

Answer 1

Answer: (B)

In ETC (Electron Transport Chain), one molecule of $NADH + H^{+}$gives rise to 2 ATP molecules, and one $FADH _{2}$ gives rise to $3$ ATP molecules.

Answer 2

In ETC of respiration, oxidation of one molecule of $NADH + H ^{+}$gives rise 3 ATP and $FADH _{2}$ produces 2 ATP.
