Suppose that the enzyme you are studying is regulated by phosphorylation. When the enzyme is phosphorylated, the Km for its substrate increases by a factor of 3, but Vmax is unaltered. At a concentration of substrate equal to the Km for the unphosphorylated enzyme, decided whether phosphorylation activates the enzyme or inhibits it. Explain your reasoning.
