E'° of the NAD+/NADH half reaction is –0.32 V.  The E'° of the oxaloacetate/malate half reaction is –0.175 V.  When the concentrations of NAD+, NADH, oxaloacetate, and malate are all 10–5 M, the “spontaneous” reaction is:

#Biochemistry

  1. Malate + NAD+ -> oxaloacetate + NADH + H+.

  2. Malate + NADH + H+ -> oxaloacetate + NAD+.

  3. NAD+ + NADH + H+ -> malate + oxaloacetate.

  4. Oxaloacetate + NADH + H+ -> malate + NAD+.
