Question

What is the advantage of storing glucose as glycogen in animals instead of as 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.

Answer 1

The correct option is C

Glucose present as monomers within the cell exerts more osmotic pressure than a single glycogen molecule, resulting in excess water within the cells.

Glucose maintains high osmotic pressure inside the cell.
