| Comments | The motor unit of ATP synthase requires 10 H+ to complete a full rotation, which results in the generation of three ATP. For each ATP, the energy of an additional proton is required to transport the substrates and products across the mitochondrial membrane. 13/3 is approximately 4.3 H+/ATP. |
