Calculate Delta G degree for the flow of electrons from NADH
Calculate Delta G degree\' for the flow of electrons from NADH to O_2 in the mitochondrial electron transport chain. NAD^+ + H^+ + 2e^- rightarrow NADH E_0\' = -0.32V F = 96.5 Kj/Mol/V 1/2 O_2 + 2H^+ + 2e^- rightarrow H_2O E_0\' = 0.82V B) Explain how this reaction is able to proceed in the opposite direction in chloroplasts.
Solution
A]
NADH + 1/2 O2 + H+ NAD+ H2O
NADH is the electron donor and O2 is the electron acceptor,
G0\' = -nFE0\'
G0\' = - (2 electrons)(96.5 kJ/volt.mol)(0.82volt(0.32volt))
G0\' = - 220 kJ/mol
