Inside an active mitochondrion, most electrons follow which pathway?

Question

Inside an active mitochondrion, most electrons follow which pathway? (A) Glycolysis → NADH → Oxidative Phosphorylation → ATP → O2 (B) Krebs' cycle → FADH2 → ETS → ATP (C) ETS → Krebs' cycle → ATP → O2 (D) Krebs' cycle → NADH + H+ → Electron transport chain → O2

Tardigrade Admin · Accepted Answer

Correct answer is (d) Krebs' cycle → NADH + H+ → Electron transport chain → O2

Q. Inside an active mitochondrion, most electrons follow which pathway?

Glycolysis $\to N A DH \to$ Oxidative Phosphorylation $\to A TP \to O_{2}$

Krebs' cycle $\to F A D H_{2} \to ETS \to A TP$

$ETS \to$ Krebs' cycle $\to A TP \to O_{2}$

Krebs' cycle $\to N A DH + H^{+} \to$ Electron transport chain $\to O_{2}$

Correct answer is (d) Krebs' cycle $\to N A DH + H^{+} \to$ Electron transport chain $\to O_{2}$
