1. (A)-(II), (B)-(III), (C)-(I), (D)-(IV)
2. (A)-(III), (B)-(III), (C)-(I), (D)-(IV)
3. (A)-(IV), (B)-(I), (C)-(III), (D)-(II)
4. (A)-(IV), (B)-(I), (C)-(II), (D)-(III)

Answer

(4) (A)-(IV), (B)-(I), (C)-(II), (D)-(III)

Solution

(A) Amylose: unbranched chain of α-D-glucose units joined by -C1 - C4 glycosidic linkages; a component of starch (plant) (IV)

(B) Cellulose: unbranched chain of β-D-glucose units joined by -C1 - C4 glycosidic linkages; plant cell walls (I)

(C) Glycogen: the storage polysaccharide of animals (animal starch), built on -C1 - C4 chains (with -C1 - C6 branch points, more highly branched than amylopectin) (II), the only animal source

(D) Amylopectin: branched chain of α-D-glucose; -C1 - C4 in the chain and -C1 - C6 at the branches; component of starch (plant) (III)

(A)-(IV), (B)-(I), (C)-(II), (D)-(III)

Answer: (4)
