The mitochondrion maintains Df=180 mV (negative inside), pHin = 8, pHout=7, [Pi] = 3 mM and ADP is present as well. How much energy is available (from the proton electrochemical gradient) for ATP synthesis under these conditions (in kJ/mol)? What [ATP]/[ADP] ratio will be established at steady-state under these conditions? What would be the [ATP]/[ADP] ratio if the enzyme had only 9 ‘c’ subunits?
