What role do hydrogen ions (H⁺) play in the electron transport chain?
A) They are pumped across the mitochondrial inner membrane against their concentration gradient (to where their concentration is high) ; as the H⁺ ions flow back to where their concentration is low, they drive ATP synthase to form ATP.
