BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Complex carbohydrates, or polysaccharides, consist of hundreds or even thousands of monosaccharides. They include starch, glycogen, cellulose, and chitin. They generally either store energy or form structures, such as cell walls, in living things. Starch is a complex carbohydrate that is made by plants to store energy.

Detailed explanation-2: -Both starches and cellulose are carbohydrates which are classified as polysaccharides since they are composed of chains of glucose molecules. While they are similar, starches can be used as energy sources by the human body while cellulose cannot.

Detailed explanation-3: -Animals store energy as glycogen, which consists of more highly branched chains of glucose. Collectively, sugars, starch, and glycogen are know as carbohydrates, and they are an important source of cellular energy.

Detailed explanation-4: -5.3. Cellulose, as is starch, is a carbohydrate. It is a structural polysaccharide, while starch is one of the storage polysaccharides.
