Why does oxygen is important for complete oxidation of Glucose?

(1) Because it is limited to the terminal stage of the process

(2) Because it drives the whole process by removing hydrogens from the system

(3) It acts as the final hydrogen acceptor not the Electron acceptor

(4) Both B and C

Why do we call it oxidative Phosphorylation?

(1) Because of the presence of oxygen

(2) Because here proton gradient is maintained by the energy of oxidation and reduction

(3) Because of the presence of ADP and oxygen

(4) Because of the presence of Phosphorylation derived by oxygen
