Identify the correct order of electron transfers in the electron transport chain starting from FADH₂. A) complex I $\rightarrow$ complex II $\rightarrow$ complex III $\rightarrow$ complex IV B) complex II $\rightarrow$ complex III $\rightarrow$cytochrome c $\rightarrow$ complex IV C) complex II $\rightarrow$ coenzyme Q $\rightarrow$complex IV $\rightarrow$ ATP synthase D) complex I $\rightarrow$ coenzyme Q $\rightarrow$ complex III $\rightarrow$ complex IV

Question

Quizplus · Accepted Answer

The correct order of electron transfers in the electron transport chain starting from FADH2 is complex II (FADH2→ubiquinone), complex III (ubiquinone→cytochrome c), cytochrome c (cytochrome c→complex IV), and complex IV (oxygen + 4H+ + 4e- → 2H2O). Option A is incorrect because it starts with complex I instead of complex II. Option C is incorrect because it includes ATP synthase before the final electron acceptor, oxygen. Option D is incorrect because it includes complex I, which is not used when starting from FADH2.
