<prompt> Which of the following is a debranching enzyme:Glycogen synthetaseGlucose-6-phosphataseAmylo alpha-1,6-glucosidaseAmylo 1,4-1,6 trans glycosylase  <response>: Debranching enzyme is a Bifunctional enzyme with two activities Glucan transferase Amylo a-1,6-glucosidase breaks the alpha 1-6 glycosidic bond present at the branch point of glycogen in glycogen breakdown. Other Options: Glycogen synthetase transfer glucose from UDP-glucose to glycogenin. Glycogen branching enzyme also known as amylo-a1,4-a1,6 trans glycosylase make glycogen branches by transferring the end of the chain onto an earlier pa a-1,6 glycosidic bond. Glucose-6-phosphatase dephosphorylates glucose-6-phosphate to free glucose.
