Understanding the energetics of the lactate dehydrogenase reaction
The standard reduction potential for (NAD+/NADH+H+) is -0.320 V, and the standard reduction potential for (pyruvate/lactate) is -0.185 V.
a. What is the standard free energy change, ΔGº’, for the lactate dehydrogenase reaction:
NADH + H+ + pyruvate→ lactate + NAD+
b. What is the equilibrium constant (Keq) for this reaction?
c. If [pyruvate] = 0.05 mM and [lactate] = 2.9 mM and ΔG for the lactate dehydrogenase reaction = -15 kJ/mol in erythrocytes, what is the (NAD+/NADH) ratio under these conditions?
