Options
- AA-3, B-2, C-4, D-1
- BA-2, B-3, C-4, D-1
- CA-2, B-3, C-1, D-4
- DA-3, B-2, C-1, D-4
Correct answer
B. A-2, B-3, C-4, D-1
Step-by-step solution
Cytochrome c is a small protein attached to the outer surface of the inner mitochondrial membrane and acts as a mobile electron carrier for the transfer of electrons between Complex III and Complex IV. Thus, A matches with 2. Ubiquinone is located within the inner mitochondrial membrane. It receives reducing equivalents from NADH dehydrogenase (Complex I) as well as from FADH₂ (Complex II). Thus, B matches with 3. Complex V is ATP synthase, which consists of two major components, F₀ and F₁ . Thus, C matches with 4.
