The Enzymes Catalase and Malate Dehydrogenase Are Both Classified as Oxidoreductases.Catalase

Multiple Choice

The enzymes catalase and malate dehydrogenase are both classified as oxidoreductases.Catalase has a heme group present at its catalytic site, whereas malate dehydrogenase has no bound cofactors or prosthetic groups and uses NAD⁺ as a coenzyme.What can you infer about these two enzymes?

A) Both use the same mechanism to transfer electrons during an oxidation-reduction reaction.
B) One uses induced fit to facilitate transfer of electrons from one group to another, while the other does not.
C) One uses specific binding sites to orient the substrate for electron transfer, while the other does not.
D) One uses covalent catalysis, while the other uses acid-base catalysis to transfer electrons.
E) One uses metal ion catalysis, while the other uses a nonmetal group to transfer electrons.
