The true statements are:
The binding of glucose to liver phosphorylase a shifts the equilibrium from the active form to the inactive form.
Muscle phosphorylase b is regulated by AMP, adenosine monophosphate.
Phosporylase kinase is activated by phosphorylation and binding of Ca2+ ions.
When glucose binds to phosphorylase a, the equilibrium of regulation shifts from active R form to inactive T form. Glycogen phosphorylase b can be activated allosterically by AMP. The increased calcium ions binds to the calmodulin subunit, which activates glycogen phosphorylase kinase. Glycogen phosphorylase kinase activates glycogen phosphorylase.
