The Standard Reduction Potential for Ubiquinone (Q or Coenzyme Q) $\Delta$

question 75

Essay

The standard reduction potential for ubiquinone (Q or coenzyme Q) is 0.045 V, and the standard reduction potential (E'°) for FAD is -0.219 V. Using these values, show that the oxidation of FADH₂ by ubiquinone theoretically liberates enough energy to drive the synthesis of ATP. The Faraday constant, , is 96.48 kJ/V · mol. $\Delta$ G'° for ATP synthesis is +30.5 kJ/mol.
