Question

Which of the following is incorrect?

• A. Amylose is branched
• B. Glycogen is also called animal starch
• C. Starch is made up of α-glucose
• D. β-glycosidic linkage for cellulose

Answer 1

The correct option is A

Amylose is branched

The explanation for the correct answer:

(a) Amylose is branched

1. Amylose is a polymer that is found in starch.
2. The monomer of amylose is glucose and it is made up of 100-1000 units of glucose units.
3. It is a linear chain compound.

The explanation for the incorrect answer:

(b) Glycogen is also called animal starch

1. Glycogen is a polysaccharide of glucose that serves as a form of energy storage in fungi and animals.
2. The polysaccharide structure of glucose shows the primary storage form of glucose in the body.
3. Glycogen is also called animal starch because it is made and stored in the cells of liver and muscles of the animals.
4. It has a similar structure to starch (amylopectin).

(c) Starch is made up of α-glucose

1. Starch is a polysaccharide of alpha glucose units.
2. it is made up of 1,4 glycosidic bonds between glucose monomers.
3. It has two forms amylose (linear chain polymer) and amylopectin (branched).
4. Starch’s primary role is to help plants store energy.

(d) β-glycosidic linkage for cellulose

1. Cellulose is a polysaccharide of glucose monomers.
2. It is made up of 1,4 beta glycosidic bond between glucose units.
3. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae.
4. Structure

Therefore, Option (a) is the correct option, Amylose is not branched it is a linear chain polymer of glucose.
