BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Carbohydrates are a group of macromolecules that are a vital energy source for the cell and provide structural support to plant cells, fungi, and all of the arthropods that include lobsters, crabs, shrimp, insects, and spiders.

Detailed explanation-2: -Carbohydrates are very important in horticultural commodities because of their contribution to the texture, flavor, color, and nutritional value of these products. Celluloses, hemicelluloses, and pectins are essential to maintaining the structure of plant cells.

Detailed explanation-3: -Glycogen and starch are storage carbohydrates found in animals and plants respectively. And cellulase is an enzyme produced by cellulose-digesting bacteria present in the gut of cattle capable of breaking down cellulose to glucose. The only structural carbohydrate in the list is chitin.

Detailed explanation-4: -In both plants and animals, carbohydrates are the most efficient source of energy. They are stored as starch and glycogen form in plants and animals. The polymeric carbohydrate starch, also known as amylum, is made up of multiple glucose units joined by glycosidic connections.
