The succinate dehydrogenase complex couples the oxidation of succinate to the reduction of ubiquinone (Q) according to the following equation. succinate + Q --> fumarate + QH2 Given that E'° for the fumarate/succinate redox pair is + 0.031V and Eº for the Q/QH2 redox pair is + 0.045V, calculate the standard free energy change (A G") for the oxidation of succinate by ubiquinone. Ag° = - 1.35 kJ/mol Ag° = - 2.7 kJ/mol OAG° = - 280 kJ/mol OAG° = + 1.35 kJ/mol Ag° = + 2.7 kJ/mol
