Enzyme X exhibits maximum activity at pH-6.3. X shows a fairly sharp decrease in its activity when the pH goes much lower than 5.8. One likely interpretation of this pH activity is that: a Glu residue on the enzyme is involved in the reaction. the enzyme uses NADH has a cofactor O the enzyme uses coenzyme A has a cofactor O a Tyr residue on the enzyme is involved in the reaction. Oa His residue on the enzyme is involved in the reaction
