D. acetyl–CoA

opcode · Answer

The electron transport chain (aka ETC) is a process in which the NADH and [FADH2] produced during glycolysis, B-oxidation, and other catabolic processes are oxidized thus releasing energy in the form of ATP. The mechanism by which ATP is formed in the ETC is called chemiosmotic phosphorolation. So to recap: ETC = changes NADH and FADH2 into ATP.
