As high energy electrons are passed along the system of electron transport chain associated with photosystem II, how does the chloroplast use this energy? A. It is used to phosphorylate NAD+ to NADPH B. It excites electrons of the reaction center of photosystem I. C. It is used to maintain a proton gradient for ATP synthesis D. It is used to break down a water molecule
What happens along an electron transport chain? 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. O Electrons store energy that can be used to break down sugar molecules. O Protons are pumped through ATP synthase, making ATP.
