Question

Name an allosteric activator of glygogen synthase, and the allosteric regulator of liver glygogen phosphorylase. Does this regulator activate the phoshorylase?

Answer 1

1.The reaction of glycogen synthase is highly regulated by allosteric effectors such as GLUCOSE6 phosphate (ACTIVATOR) and by phosphorylation reaction(DEACTIVATING) .glycogen synthase is also regulated by PROTEIN PHOSPHATASE1 which ACTIVATES it via DEPHOSPHORYLATION.

2. The glycogen phosphorylase is regulated by both ALLOSTERIC AND BY PHOSPHORYLATION. hormones such as EPINEPHRINE, INSULIN, GLUCAGON regulate it.

as seen above, THESE ARE THE REGULATOR WHICH ACTIVATE THE PHOSPHORYLASE
