Which of the following enzyme is common between glycogenesis and glycogenolysis?
High-Yield Explanation
Ans: D.PhosphoglucomutasePhosphoglucomutase enzyme is common between glycogenesis & glycogenolysis.Reaction catalyzed by phosphoglucomutase is reversible.Hence, glucose 6-phosphate can be formed from glucose I-phosphate.In liver & kidney, (not in muscle) glucose 6-phosphatase hydrolyzes glucose 6-phosphate a glucose a Increases blood glucose concentration.(Ref Harper's 29/e p180; Harper 30/e p176, 177, 28/e p158, 333).
