What is the function of all enzymes? -make more products from less reactants
-catalyze the breakdown of hard to digest foods
start chemical reactions
-increase the speed of -chemical reactions

What happens as electrons move along the chain of molecules known as the electron transport chain? they gain energy, which causes atp molecules to lose phosphate groups. they gain energy, which causes h *ions to join with oxygen to produce water. they lose energy, which is then used by the cell to make atp. they lose energy, which is then used to break down atp.
