Answer the following question given this paragraph: Many enzymes are simple proteins consisting entirely of one or more amino acid chains. Other enzymes contain a nonprotein component called a cofactor that is necessary for the enzyme's proper functioning. There are two types of cofactors: inorganic ions [e. , zinc or Cu(I) ions] and organic molecules known as coenzymes. Most coenzymes are vitamins or are derived from vitamins. Q: Many enzymes are simple proteins consisting entirely of one or more of these? A:
