What happens along an electron transport chain? Electrons are passed from a reducing agent to an oxidizing agent, releasing free energy at each step. Electrons are passed from molecule to molecule, gaining potential energy at each step. Electrons store energy that can be used to break down sugar molecules. Protons are pumped through ATP synthase, making ATP.
