In the tricarboxylic acid cycle, L-malate is oxidized to oxaloacetate, using NAD+ as an oxidizing agent. Using the half reactions from the given table, what is the reaction of this reduction-oxidation? Oxaloacetate + NAD+ –→ L-Malate + NADH L-Malate + Oxaloacetate -- NAD* + NADH L-Malate + NAD+ – → Oxaloacetate + NADH L-Malate -- Oxaloacetate + NAD+ + NADH
