• A. Glycolysis $\to NADH \to$ Oxidative Phosphorylation $\to ATP \to O_2$
• B. Krebs' cycle $\to FADH_2 \to ETS \to ATP$
• C. $ETS \to$ Krebs' cycle $\to ATP \to O_2$
• D. Krebs' cycle $\to NADH + H^{+} \to$ Electron transport chain $\to O_2$

Answer 1

Answer: (D)

Correct answer is (d) Krebs' cycle $\to NADH + H^{+} \to$ Electron transport chain $\to O_2$
