Phosphorylation could activate an allosteric enzyme by the

Phosphorylation could activate an allosteric enzyme by _____ the amount of the T-form. Phosphorylation could inhibit a Michaelis-Menten enzyme by ____ the Km of the enzyme for its substrate.

Solution

Answer will be option D.

In case of allosteric enzyme phoshorylation results activation of allosteric enzyme.T-form of allosteric enzyme is the inactivated form so it will decrease as the enzyme get activated.In case of Michaelis-Menten enzyme phosphorylation inhibit it so the Km will be higher that means the affinity of the enzyme toward substrate gets low and enzyme is inhibited.

So option A,B and C is wrong.

Hence option D is correct option.
