Fo-F1 ATPase. The energy for ATP synthesis from ADP and Pi is provided by the downhill transport of protons through the rotary FoF1 ATP synthase (lecture 22). The enzyme has 3 a-b and 12 ‘c’ subunits. 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? Remember that full revolution of the crank (gamma subunit) produces 3 ATP.
