The standard reduction potentials (E®) for the following half reactions are given. Oxaloacetate + 2H* + 2e malate E--0.166 V NAD* + 2H* + 2e NADH+ H E-0.320 V If you mixed oxaloacetate, malate, NAD, and NADH together, all at I M concentrations and in the presence of malate dehydrogenase, which of the following would happen initially? Oxaloacetate and malate would become oxidized; NAD* and NADH would become reduced. Malate would become oxidized, NAD would become reduced.

Oxaloacetate and malate would become oxidized; NAD* and NADH would become
reduced.
Malate would become oxidized, NAD* would become reduced.
Oxaloacetate would become reduced, NADH would become oxidized.
No reaction would occur because all reactants and products are already at their
standard concentrations.
