Biology
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

Explanation:
1. The enzyme _Glycogen phosphorylase_ removes terminal glucose residues from glycogen by cleaving _α-[1→4 ]-glycosidic bond_linkages.
2. Enzyme activity stops when the enzyme reaches a point _Four_ glucose residues from a branch point, which is a(n) _α-[1→6]-glycosidic bond_ linkage.
3. The _glucosyltransferase_ of the debranching enzymes moves three glucose residues to another branch, connecting them by a(n) _α-[1→6]-glycosidic bond_ linkage.
4. The _glucosidase_ activity of the debranching enzyme removes the glucose at its _α-[1→6]-glycosidic bond_ linkage.
5. The enzyme _glucosidase_ continues removing terminal glucose residues.
