Answer: B)
Explanation:
The glycoprotein and glycolipid carbohydrate chain forms the hydrogen
bond with water molecules to help stabilize the membrane structure.
When it comes to glycoproteins and glycolipids and their bond we can say that their carbohydrate chain is forming a hydrogen bond with water molecules that are surrounding the cell and thus. In this case, they are helping in the stabilization of membrane structure. They are used as receptor molecules.
Answer:
