How is oxidative phosphorylation different than the ETC?


Oxidative phosphorylation is the synthesis of ATP from ADP and Pi, using the energy provided by an electrochemical gradient. The ETC is a system of electron carriers that use released energy to produce that electrochemical gradient. They are very closely related in overall function, but are distinctly separate in what they do. For example, no electrons are moved by the ATP synthase, and no ATP is produced by the ETC. They work together, but do not overlap.
