At the end of the chain of enzyme complexes the  electrons  join  oxygen H2O  on the inside of the mitochondria Energy now stored in proton gradient resulting from accumulation of protons in space  between the two mitochondrial membranes End product of electron transport system is a  gradient of protons  across the inner  membrane of the mitochondria - high concentration in inner membrane space - low concentration in inner compartment (matrix) The proton gradient is used to do work ( form ATP ) Gradient favors movement of protons across inner membrane But remember inner membrane is impermeable to protons So, they have to move across the membrane they have to pass through enzymes Enzyme that protons pass through is  mitochondrial ATP synthase  (synthesizes  ATP) As protons move through the enzymes the energy of their passing is used to
