- (a) Calculate the standard free energy change as a pair of electrons is trans- ferred from succinate to molecular oxygen in the mitochondrial respira- tory chain. (b) Based on your answer in part a, calculate the maximum number of protons that could be pumped out of the matrix into the intermembrane space as these electrons are passed to oxygen. Assume 25 °C, ApH = 1.4; Aựt = 0.175 V (matrix negative). (c) At which site(s) are these protons pumped?
