The enzyme that converts phenylalanine to tyrosine is an oxidoreductase that requires BH₄, which is converted to BH₄OH over the course of the reaction. BH₄ is a(n) A) enzyme. B) protein. C) coenzyme. D) amino acid. E) lipid.

Question

Quizplus · Accepted Answer

BH₄ is described as being converted to BH₄OH during the reaction, indicating that it is participating as a coenzyme. Enzymes and proteins are not converted in this way during reactions, and amino acids and lipids are not typically involved as cofactors in enzyme-catalyzed reactions.
