B) Energy: cellulose and chitin
Structure: glycogen and starch
C) Energy: chitin and glycogen
Structure: cellulose and starch
D) Energy: cellulose and starch
Structure: chitin and glycogen
The answer is option A
Explanation:
Carbohydrates are biological molecules in living systems. Polysaccharides are a type of carbohydrate molecules, which are polymers made up of monomers called monosaccharides. Monosaccharides such as glucose, fructose etc. are joined together by glycosidic bonds to form this polysaccharides. However, polysaccharides found in nature are classified based on their function in their found organisms.
1) Energy: Glycogen and starch are the two carbohydrate polymers that function in this aspect. They are both made up of long chains of glucose unit linked by α glycosidic bonds. Glycogen stores energy in the animal cells while starch stores energy in plant cells.
2) Structure: Cellulose and Chitin are the two carbohydrate polymers involved in this function. Cellulose is made up of glucose monomer linked together by β glycosidic bonds. It is the major structural component found in the cell wall of plant cells. Chitin is also a polymer of N-acetyl glucosamine and the major structural component of the cell wall of oorganisms like fungi.
