Glycogen is a branched polymer of glucose. Glucose residues are linked linearly by α-1, 4 glycosidic bonds (glycosidic bonds formed between C-1 of one glucose with the C-4 of the next). After every 10-14 units, a side chain branch occurs that attach at C-6 of a glucose unit by α-1, 6 glycosidic linkages.

Explanation:

1. X - 1, 4-α-glycosidic bonds:
- In a glycogen molecule, successive glucose units are joined together by 1, 4-α-glycosidic bonds. This means that the glucose molecules are linked together by bonding the first carbon of one glucose molecule to the fourth carbon of the next glucose molecule.

2. Y - 1, 6-α-glycosidic bonds:
- The branches in a glycogen molecule are linked together by 1, 6-α-glycosidic bonds. This means that a branch of the molecule is attached to the main chain by bonding the first carbon of one glucose molecule to the sixth carbon of another glucose molecule.

Therefore, in a glycogen molecule, X represents the 1, 4-α-glycosidic bonds that join successive glucose units, and Y represents the 1, 6-α-glycosidic bonds that link the branches together. So, the correct identification is X - 1, 4-α-glycosidic bonds and Y - 1, 6-α-glycosidic bonds.
