2 cyt. c
3 cyt.
4 cyt. ${{a}_{3}}$
Explanation:
(d) Terminal cytochrome of respiratory chain is cyt ${{a}_{3}}$. cyt ${{a}_{3}}$ posseses two copper centres. It helps in transfer of electrons to oxygen.

In the electron transport system, the final acceptor of electron is:
1 cytochrome b
2 ubiquinone (substance A)
3 oxygen
4 cytochrome ${{\text{a}}_{3}}$
Explanation:
(c) In the electron transport system, the final acceptor of proton is oxygen. Oxygen functions as the terminalacceptor of electrons and is reduced to water along with the hydrogen atoms in mitochondrial matrix. It drives whole process by removing hydrogen from system.

Electron Transport System (ETS) is present in a eukaryotic cell in the:
1 inner mitochondrial membrane.
2 mitochondrial matrix.
3 Inter-membrane space.
4 cytoplasm.
Explanation:
(a) Electron transport chain is a series of coenzymes and cytochromes that takes part in the passage of electrons from a chemical to its ultimate acceptor. It takes place on the cristae of mitochondria found on the inner surface of the membrane of mitochondria.
