Lactate + NAD+ ----------> Pyruvate + NADH + H+
E0'
= Standard Reduction Potential of
E0' (reduction half reaction) - Standard Reduction
Potential of
E0' (oxidation half cell).
Here NAD+ undergoing reduction and lactate is undergoing oxidation.
E0'of
overall reaction = [E0'
for (NAD+ to NADH + H+)] - [E0'
for pyruvate to lactate]
=-0.32-(-0.19) = -0.32+0.19=-0.13V.
E0'of
overall reaction=-0.13 Volts.
