Answer:
3.inactivated by phosphorylation.
Step-by-step 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.
