Question

Glycogen synthase is an enzyme important for making glycogen. In response to glucagon, glycogen synthase is Glycogen synthase is an enzyme important for making glycogen. In response to glucagon, glycogen synthase is 1.inactivated by removing a phosphate group (dephosphorylation). 2.activated by phosphorylation. 3.inactivated by phosphorylation. 4.activated by removing a phosphate group (dephosphorylation).

Answer 1

Answer:

3.inactivated by phosphorylation.

Explanation:

Glycogen synthase is an enzyme, glycosyltransferase  that is involved in the conversion of glucose into glycogen. There are two ways of the regulation of glycogen synthase:

• allosteric regulation- via glucose-6-phosphate, which is activator of the enzyme
• by phosphorilation-it deactivates the enzyme and it is triggered by glucagon from the pancreas.

The regulation of glycogen synthase is very important for  glycogen metabolism and glucose storage.
