In оxidаtive phоsphоrylаtion, NADH аnd FADH₂ donate electrons to the electron transport chain, leading to ATP synthesis. NADH donates its electrons at Complex I, which contributes to pumping 10 protons (H⁺) across the inner mitochondrial membrane per NADH oxidized. FADH₂ donates electrons at Complex II, bypassing Complex I, and contributes to pumping only 6 protons across the membrane. Since approximately 4 protons are needed to synthesize 1 ATP, the estimated ATP yield is: NADH: 104=2.5frac{10}{4} = 2.5 ATP FADH₂: 64=1.5frac{6}{4} = 1.5 ATP Based on this information, which of the following best explains the difference in ATP yield between NADH and FADH₂?
