Question

Quizplus · Accepted Answer

The electron transport chain is a series of redox reactions that occur in the inner membrane of the mitochondria. The chain consists of a series of electron carriers that transfer electrons from one molecule to the next, ultimately leading to the production of ATP. Substitution reactions do not occur in the electron transport chain, and it does not take place in the cytoplasm of prokaryotic cells. The electron transport chain is driven by the movement of electrons, not ATP consumption.
