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.
Correct option (C) Glucose present as monomers within the cell exerts more osmotic pressure than a single glycogen molecule, resulting in excess water within the cells.
Explanation:
Glucose is a monosaccharide and osmotically active molecule which increase osmotic pressure in cell so water enters in cell while glycogen is osmotically inert molecule does not change the osmotic pressure.
