I understand that every electron carrier of the ETC goes from higher to lower oxidation potential, and that the main point of ETC is creating the proton motive force to run the ATP synthase. However, I don’t yet understand what difference it makes to use electron transfer in order to pump hydrogen ions, to use any other way to pump hydrogens out; how do electrons relate to the hydrogen atoms being pumped?
