Question

During glycogenolysis, glycogen is broken down and converted to glucose-6-phosphate, which can enter glycolysis or be used by the liver to raise blood glucose levels. Complete the following sentences describing glycogen breakdown. Move the appropriate term to each blank. Some terms will be used more than once, and two terms will not be used at all.

1. The enzyme ________ removes terminal glucose residues from glycogen by cleaving ________ linkages.



2. Enzyme activity stops when the enzyme reaches a point _______ glucose residues from a branch point, which is a(n) ________ linkage.



3. The ________ of the debranching enzymes moves three glucose residues to another branch, connecting them by a(n) ________ linkage.



4. The ________ activity of the debranching enzyme removes the glucose at its ________ linkage.



5. The enzyme ________ continues removing terminal glucose residues



Answer Choices: Glucosidase, Phosphoglucomutase, three, four, glycogen phosphorylase, alpha (1,6), alpha (1,4), transferase

Answer 1

During glycogenolysis, the enzyme glycogen phosphorylase removes terminal glucose residues from glycogen by cleaving alpha (1,4) linkages. Enzyme activity stops when the enzyme reaches a point three glucose residues from a branch point, which is a(n) alpha (1,6) linkage. The transferase of the debranching enzymes moves three glucose residues to another branch, connecting them by a(n) alpha (1,6) linkage.

Step-by-step explanation:

1. The enzyme glycogen phosphorylase removes terminal glucose residues from glycogen by cleaving alpha (1,4) linkages.

2. Enzyme activity stops when the enzyme reaches a point three glucose residues from a branch point, which is a(n) alpha (1,6) linkage.

3. The transferase of the debranching enzymes moves three glucose residues to another branch, connecting them by a(n) alpha (1,6) linkage.

4. The alpha (1,6) activity of the debranching enzyme removes the glucose at its alpha (1,6) linkage.

5. The enzyme glycogen phosphorylase continues removing terminal glucose residues
