Question

Glucose, a monosaccharide, is found in three different polysaccharides: starch, glycogen, chitin. There are differences between

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:

Glucose is a monosaccharide which is used for instant source of energy. Whenever there is excess glucose in the body, it is stored in the body for future use in the form of glycogen molecules. Glycogen is a long branched chain polysaccharide which is formed by joining the monomeric glucose units through glycosidic linkage. Glycogen has α--1,4 & α--1,6 glycosidic linkage.

Option A is somewhat correct but the reason for not choosing option A is because starch exists in 2 forms which are amylose and amylopectin. Although amylose is helical and unbranched yet amylopectin is a branched polymer. In the option it is not given anywhere that starch is a branched polymer.

Answer 2

Answer: A) Glucose molecules are joined in a long chain to make starch that is easily digested for energy.

Explanation: Cellulose is a structural carbohydrate, not easily digested.
