Question

Quizplus · Accepted Answer

Enzyme X is catalyzing a redox reaction, where a metal cofactor is being reduced and then reoxidized. Oxidoreductases are enzymes that catalyze redox reactions and are responsible for electron transfer in the catalyzed reaction. Therefore, Enzyme X falls under the category of oxidoreductases.
