Glycogen synthase catalyzes all of the stages of glycogen synthesis. true or false

False.

Glycogen synthase does not catalyse all the steps in glycogen synthesis.

Explanation:

Glycogen synthesis or glycogenesis is the synthesis of glycogen from glucose. It requires ATP and it take place in it cytosol. Glycogen synthesis involves six steps and glycogen synthase take part in only one step.

Glycogen synthase is a key enzyme in glycogen synthesis. It is glycosyltransferase that catalyses the reaction of UDP glucose and (1,4-a-D-glycosyl)n to give (1,4-a-D-glycosyl)n+1.

substitution is the answer in this case
