試題詳解

 1. Cleavage of glycogen terminal glucose is catalyzed by glycogen phosphorylase. 

 2. The breaksdown of glycogen to generate Glucose-6-phosphate needs no ATP.

 3. Transferase activity in glycogen debranching enzyme catalyzes the transfer of shorter α(1→)6 linked glucose chain to another o(1-)6 linked glucose chain for further cleavage reaction.

 4. Glucosidase activity in glycogen debranching enzyme catalyzes the cleavage ofα(1→6) linked glucose for complete breaking down the branch in glycogen
