What must also take place is we must somehow convert the glycogen synthase B in the inactive form back to the glycogen synthase A. And what happens in this particular case is we have to activate another enzyme known as PP one where PP one stands for protein phosphatase one because it's protein phosphatase one in the active form that defosphorylates glycogen synthase B and forms the active form of glycogen synthase A. And only glycogen synthase A can actually stimulate glycogenesis. So we see that from steps 12345 and six insulin ultimately causes the inactivation of glycogen synthase kinase, the enzyme that keeps glycogen synthase in the inactive form. Now, in order to actually transform this glycogen synthase B into the active form, the glycogen synthase A, our liver cells must initiate glycogenesis. And to do this they have to actually activate PP one because it's protein phosphatase one that stimulates this conversion.
