Question

Can someone answer this

Answer 1

Answer:

B) Glucose molecules are joined in long, branched chains to make glycogen that allows for long term energy storage in animals.

Explanation:

Starch:

Starch is a complex polysaccharide made up of glucose molecules bonded via glycosidic linkage. Starch is primarily of two forms:

1. A linear polymer of glucose molecules bonded together by α 1,4 glycosidic linkage known as amylose.
2. A highly branched, complex polymer of glucose bonded together by α-1,4 and α-1,6 glycosidic linkages known as amylopectin. The α-1,6 linkage is responsible for branching in amylopectin.

Unlike starch, cellulose is a polymer consisting of linear chains of glucose units. Cellulose is indigestible for humans. It is excreted as dietary fiber.

Glycogen:

Glycogen is the primary form of glucose storage in animals, fungi and bacteria. Glycogen is also a complex, branched polymer of glucose units. Glycogen mainly contains amylopectin i.e a highly branched form of glucose polymer that contains α-1,4 and α-1,6 glycosidic linkages.

Chitin:

Chitin is a long chain polymer of modified form of glucose i.e. N-acetylglucosamine which is a nitrogen containing derivative of glucose. N-acetylglucosamine monomers are linked together through glycosidic bonds.
