Hint:

In biochemistry, the type of glycosidic bonds (α or β) and the organism (plant or animal) help classify carbohydrates.

Answer 1

The Correct Option is B

To address this matching task, it is necessary to establish the relationships between items in List - I and List - II.

List - I: Elements and Their Definitions:

1. Amylase: An enzyme that catalyzes the breakdown of starch into sugars by hydrolyzing \( \alpha \)-C1-C4 glycosidic bonds, commonly found in plants.
2. Cellulose: A polysaccharide composed of \( \beta \)-C1-C4 glycosidic bonds, forming the structural component of plant cell walls. Its \( \beta \)-linkages differentiate it structurally from starch.
3. Glycogen: The animal storage form of glucose, characterized by \( \alpha \)-C1-C4 and \( \alpha \)-C1-C6 glycosidic linkages. It functions as an energy reserve, analogous to plant starch but with increased branching.
4. Amylopectin: A constituent of starch, featuring \( \alpha \)-C1-C4 main chains with \( \alpha \)-C1-C6 branching points, present in plants.

List - II: Descriptions:

1. \( \beta \)-C1-C4 plant: Corresponds to the structural classification of cellulose.
2. \( \alpha \)-C1-C4 animal: Generally pertains to simple \( \alpha \)-linkages in unbranched animal polysaccharides.
3. \( \alpha \)-C1-C4 \( \alpha \)-C1-C6 plant: Describes the structure of amylopectin, an \( \alpha \)-linked, branched polysaccharide found in plants.
4. \( \alpha \)-C1-C4 plant: Denotes the enzymatic activity of amylase on \( \alpha \)-C1-C4 bonds within plant starches.

Matching Results:

The correct pairings are established as follows:

• (A) Amylase: Corresponds to (IV) \( \alpha \)-C1-C4 plant.
• (B) Cellulose: Corresponds to (I) \( \beta \)-C1-C4 plant.
• (C) Glycogen: Corresponds to (III) \( \alpha \)-C1-C4 \( \alpha \)-C1-C6 plant.
• (D) Amylopectin: Corresponds to (II) \( \alpha \)-C1-C4 animal

Selected Option:

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