Question

Which form of the glycogen synthase is active in synthesizing glycogen?

Answer 1

-glycogen synthase

a= (nonphosphorylated) more active form-glycogen synthase

b= (phosphorylated) less active form

Answer 2

Explanation:

In glycogen breakdown, phosphorylase kinase phosphorylates GPb to the more active form, GPa. In glycogen synthesis, phosphorylase kinase phosphorylates the active form of Glycogen Synthase (GSa), and converts it into the usually inactive b form (called GSb).
