Choose the correct path taken by a pair of electrons as they travel down the electron-transport chain. A) NADH → Complex I → CoQ → Complex III → Cytochrome c → Complex IV → O₂ B) FADH₂ → Complex I → CoQ → Complex III → Cytochrome c → Complex IV → O₂ C) NADH → Complex I → Complex II→ Complex III → Cytochrome c → Complex IV → O₂ D) FADH₂ → Complex II → CoQ → Complex III → Cytochrome c → Complex IV → O₂ E) A and D

Question

Quizplus · Accepted Answer

The correct paths for electron transport are from NADH through Complex I (A) and from FADH2 through Complex II (D), both converging on CoQ, then moving through Complex III, Cytochrome c, Complex IV, and finally to oxygen.
