31. The difference in pH between the internal and external surfaces of the inner mitochondrial membrane is 1.4 pH units (external side acidic). If the membrane potential is 0.06 V (inside negative), what is the free energy change on transporting 1 mol of protons across the membrane from outside to inside at 25°C?

Question

For the mitochondrial membrane described in pic, how many protons must be transported to provide enough free energy for the synthesis of 1 mol of ATP (assuming standard biochemical conditions)?

31. The difference in pH between the internal and external surfaces of
the inner mitochondrial membrane is 1.4 pH units (external side acidic).
If the membrane potential is 0.06 V (inside negative), what is the free
energy change on transporting 1 mol of protons across the membrane
from outside to inside at 25°C?
