BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Cellulose is the single most common biochemical compound in living things. It forms the cell walls of plants and certain algae. Like most other animals, humans cannot digest cellulose, but it makes up most of the crucial dietary fiber in the human diet.

Detailed explanation-2: -The most important structural component of plant cell walls is cellulose. Cellulose is a carbohydrate found in the cell wall of plants. The carbohydrate is a polysaccharide structure.

Detailed explanation-3: -Starch is the most common digestible storage polysaccharide in plants and cellulose is a major structural component of plant cell walls (Figure 3).

Detailed explanation-4: -Cellulose and chitin are examples of structural polysaccharides. Cellulose is used in the cell walls of plants and other organisms and is said to be the most abundant organic molecule on Earth.

Detailed explanation-5: -Therefore, Cellulose is the most abundant polysaccharide on earth. Chitin is found in the exoskeleton of insects, and the cell wall of fungi.
