BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Polysaccharides are major classes of biomolecules. They are long chains of carbohydrate molecules, composed of several smaller monosaccharides. These complex bio-macromolecules functions as an important source of energy in animal cell and form a structural component of a plant cell.

Detailed explanation-2: -Polysaccharides generally perform one of two functions: energy storage or structural support. Starch and glycogen are highly compact polymers that are used for energy storage. Cellulose and chitin are linear polymers that are used for structural support in plants and animals, respectively.

Detailed explanation-3: -Glycogen is an even more highly branched polysaccharide of glucose monomers that serves the function of storing energy in animals.

Detailed explanation-4: -So for storage purposes, polysaccharides are better because they are not susceptible to degradation. Moreover, storing monosaccharides will create hypertonic conditions inside the cell which will lead to lysis of cells due to osmotic pressure, so it is more helpful for cells to store polysaccharides.

Detailed explanation-5: -Functions of Polysaccharides Storage polysaccharides: Polysaccharides such as starch and glycogen are called storage polysaccharides because they are stored in the liver and muscles to be converted to energy later for body functions. Starch is found in plants whereas glycogen is found in animals.
