Question

Inside an active mitochondrion, most electrons follow which pathway ?

• A. Glycolysis $\rightarrow NADH \rightarrow$ Oxidative Phosphorylation $\rightarrow ATP \rightarrow O_2$
• B. Krebs’ cycle $\rightarrow FADH2 \rightarrow ETS \rightarrow ATP$
• C. $ETS \rightarrow$ Krebs’ cycle $\rightarrow ATP \rightarrow O_2$
• D. Krebs’ cycle $\rightarrow NADH + H+ \rightarrow$ Electron transport chain $\rightarrow O_2$

Answer 1

Answer: (D)

Correct answer is (d) Krebs’ cycle $\rightarrow NADH + H+ \rightarrow$ Electron transport chain $\rightarrow O_2$
