What is the advantage of storing glucose as glycogen in animals instead of a monomeric glucose?

Question

What is the advantage of storing glucose as glycogen in animals instead of a monomeric glucose? (A) Energy obtained from glycogen is more than that from the corresponding glucose monomers (B) Glucose present as monomers within the cell exerts more osmotic pressure than a single glycogen molecule, resulting in loss of water from the cells (C) Glucose present as monomers within the cell exerts more osmotic pressure than a single glycogen molecule, resulting in excess water within the cells (D) Glycogen gives more rigidity to the cells

Tardigrade Admin · Accepted Answer

Glucose is a monosaccharide and an osmotically active molecule which increases osmotic pressure in cell. So, water enters in cell while glycogen is osmotically inert molecule does not change the osmotic pressure. This is the reason why glucose is not stored in the cell instead glycogen is stored in the animal body.
