Solution

The correct option is D Cyt a3
Cytochromes

The ETS or Electron Transport System is formed by multiple complexes at different energy levels which in turn are formed by certain coenzymes and cytochromes.

The coenzymes are the proton carriers and cytochromes are electron carriers in ETS.

The terminal complex IV is formed by cyt a and Cyt a3. Electron from cyt a3 finally gets accepted by oxygen.

Final answer: (D) Cyt a3
