Q24 Muscle glycogen phosphorylase, an enzyme that provides glucose to the muscle for energyproduction, gives the following activity. The middle curve shows activity with no AMP or ATPpresent. The other curves show either AMP or AMP + ATP as labeled.

Enzymes are highly specialized proteins that have extraordinary catalytic power, greater than that of inorganic catalysts. They are highly specific for their substrates. They function effectively in aqueous solution under mild conditions of temperature and pH. Enzymes catalyze numerous amount of reactions including degradation of nutrients, synthesize biological macromolecules, conserve and transform chemical energy.when the function of only enzyme is activated by allosteric activator, the Km of the activated enzyme decreases as the specificity of the enzyme to the substrate increases. Similarly, when inhibitor is used, it reduces the specificity of the enzyme to the substrate. competitive inhibitor binds to the active site of the enzyme and reduces the specificity of the enzyme to the substrate. It increases the Km but does not affect the Vmax. For noncompetitive inhibition, Km remains same but Vmax reduces. Therefore, 1)AMP is Allosteric activator of glycogen phosphorylase 2)ATP is Allosteric inhibitor of glycogen phosphorylase
