Answer:
a) the oxidizing agent.
Explanation:
In the citric acid cycle, malate is dehydrogenated into oxaloacetate and the reaction is catalyzed by malate dehydrogenase. The released electrons are accepted by NAD+. So, NAD+ is reduced into NADH. The substances that accept electrons during chemical reactions and are reduced to oxidize the other substances are called oxidizing agents. NAD+ serves as an oxidizing agent as it accepts electrons to oxidize malate into oxaloacetate.
Hi,

Active site
A reactant
binds to an enzyme in a region known as the active site during a reaction. The active site is the
most important part of the enzyme because it is where the chemical reaction
happens. It usually contains three to four amino acids and a binding site that
binds the substrate and prepares it for catalysis.
