These protein kinases then go on to deactivate glycogen synthase kinase into its inactive form. So it stimulates the inactivation of this molecule. Now, this molecule in the active state keeps the glycogen synthase A in the inactive state. But as soon as we inactivate it now there's nothing that actually transforms the glycogen synthase A into the glycogen synthase B. But we still need that molecule, the protein phosphatase One, to stimulate the conversion of this inactive glycogen synthase into the active form for us to actually form the glycogen molecules. And so this is what happens here.
