Question

Quizplus · Accepted Answer

High-energy electrons enter the electron transport chain by way of NADH and FADH₂. Energy is captured through a series of reactions that release a small amount of energy each time. During these oxidation-reduction reactions each of the carriers become reduced and then oxidized as electrons move down the system. As the pair of electrons is passed from carrier to carrier, energy is released in small amounts and captured for ATP production.
