If the atp synthase for an organism contains 15 c subunits, how many protons must be pumped across the inner mitochondrial membrane per each new atp that is synthesized by atp synthase? (don't forget to consider transport of the reactants.)

2.if five (5) molecules of fructose 6-phosphate are oxidized via glycolysis, the pdc, and the cac in a kidney cell, how many protons are pumped into the inner membrane space at etc complex i?
