COO FAD 3. The succinate dehydrogenase reaction in the direction it proceeds within the CAC is shown below (left to right): FADH Coo H-C-H HC-H dehydrogenase -OOC Succinate Fumarate Succinate " Coo AG - 0 kJ/mol a) Calculate the standard reduction potential for the overall reaction above. (2 marks) b) Based on the reduction potential, calculate and compare your standard transformed free energy change to the textbook value (above), and venture to explain any discrepancies. (3 marks) c) Assuming the temperature of the cell is 37 C, calculate the equilibrium ratio of oxidized to reduced cofactor when the ratio of oxidized product to reduced substrate is 1.2
