Glucose, a monosaccharide, is found in three different polysaccharides: starch, glycogen, chitin. There are differences between
the structure and function of the glucose arrangement found in these polysaccharides. Which statement CORRECTLY identifies
the difference in glucose structure in one of these polysaccharides?

a) glucose molecules are joined in a long chain to make starch that is easily digested for energy

b) glucose molecules are joined in long branched chains to make glycogen that allows for long term energy storage in animals

c) glucose molecules are joined in long chains with hydrogen bonds connecting multiple chains to make cellulose which is easily broken down for quick digestion

d) glucose molecules with attached amino groups are joined in long chains by a peptide bond to make chitin which makes up the cell wall of some bacteria and fungi

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.
