Vedclass · Answer

(B) In the electron transport chain $(ETC)$,the final step involves the transfer of electrons to oxygen.Cytochrome $a_{3}$ (part of cytochrome $c$ oxidase complex) transfers electrons to molecular oxygen $(O_{2})$.Oxygen acts as the terminal electron acceptor and combines with protons $(H^{+})$ to form water $(H_{2}O)$.Therefore,molecular $O_{2}$ is the terminal electron acceptor in aerobic respiration.

Which one of the following is the terminal electron acceptor?
