3.Calculate the amount of free energy required (or released) to allow electron transport in the ETC to be spontaneous from NADH to ubiquinone under standard conditions based on two electrons moving through the system.  This occurs at 25°C.

 

½ O2 + 2e + 2H+ ® H2O                            E°´ = 0.815 V

NAD+ + 2e +H+ ® NADH                           E°´ = -0.315 V

NADP+ + H+ + 2e ® NADPH                     E°´ = -0.320 V

FAD + 2e +2H+ ® FADH2                          E°´ = -0.219 V

Ubiquinone + 2H + 2e ® Ubiquinol      E°´ =  0.045 V
