What is the Electron Transport Chain

Question

What is the electron transport chain?
A)a series of redox reactions
B)a series of substitution reactions
C)reactions driven by ATP consumption
D)reactions occurring in the cytoplasm of prokaryotic cells
E)a series of condensation reactions

Accepted Answer

The electron transport chain is a series of redox reactions where electrons are transferred from electron donors (such as NADH) to electron acceptors (such as oxygen) through a series of membrane-bound electron carriers, resulting in the generation of a proton gradient across the membrane that is used to synthesize ATP.
