Oxidative Phosphorylation MDCAT Quiz with Answers

Oxidative phosphorylation is the last step of cellular respiration, in which energy from high-energy electrons is used to drive the synthesis of ATP. It takes place in the inner mitochondrial membrane and depends on the electron transport chain (ETC) and chemiosmosis. This is the most efficient method for the production of ATP; as many as 32-34 ATPs are produced per glucose molecule. In the process of oxidative phosphorylation, electrons carried by NADH and FADH₂ are passed through the ETC, a series of protein complexes and mobile carriers located in the inner mitochondrial membrane. The flow of electrons causes pumping of protons (H⁺) across the inner membrane, resulting in a proton gradient. This gradient drives the enzyme ATP synthase, which catalyzes the synthesis of ATP as protons flow back into the mitochondrial matrix. Oxygen is the final electron acceptor, and it combines with electrons and protons to form water. The MDCAT students have to learn the detail about oxidative phosphorylation in the bioenergetic and metabolic pathway.
