Enzyme X exhibits maximum activity at pH = 10.5. X shows a fairly sharp decrease in its activity when the pH goes much lower than 9.5. One likely interpretation of this pH activity is that: a. A His residue on the enzyme is involved in the reaction b. a Glu residue on the enzyme is involved in the reaction c. a Tyr residue on the enzyme is involved in the reaction d. the enzyme uses NADH has a cofactor e. the enzyme uses coenzyme A has a cofactor Please explain why, thanks!
