Characteristics of Electron Transport Chain Components A. Complex I (NADH Dehydrogenase) 1. Transfers electrons from FADH2 to ubiquinone. B. Complex II (Succinate Dehydrogenase) 2. Acts as the final electron acceptor, forming water. C. Complex IV (Cytochrome c Oxidase) 3. Transports electrons from NADH to ubiquinone. D. Ubiquinone (Coenzyme Q) 4. Transfers electrons from complex III to complex IV.

Options

  1. AA - 3, B - 1, C - 2, D - 4
  2. BA - 1, B - 3, C - 2, D - 4
  3. CA - 2, B - 1, C - 4, D - 3
  4. DA - 3, B - 4, C - 1, D - 2

Correct answer

A. A - 3, B - 1, C - 2, D - 4

Step-by-step solution

A - 3: Complex I (NADH Dehydrogenase) transfers electrons from NADH to ubiquinone. B - 1: Complex II (Succinate Dehydrogenase) transfers electrons from FADH2 to ubiquinone. C - 2: Complex IV (Cytochrome c Oxidase) is responsible for transferring electrons to oxygen, forming water. D - 4: Ubiquinone (Coenzyme Q) transfers electrons from complex III to complex IV.
