Answer :
Answer:
Decreasing, Increasing.
Explanation:
Phosphorylation could activate an allosteric enzyme by decreasing the amount of the T-form. In the case of allosteric enzyme phosphorylation results in the form of activation of allosteric enzyme. T-form of the allosteric enzyme is present in the inactivated form, so which is decrease as the enzyme is getting activated.
Michaelis-Menten enzyme by increasing the Km of the enzyme for its substrate. In this case, Michaelis-Menten enzyme phosphorylation is inhibited so that the Km is higher. Which is defined as the affinity of the enzyme for the substrate is low and the enzyme is inhibited.
