JEE Chemistry 2025 Question with Solution

Given: List - I contains Amylase, Cellulose, Glycogen and Amylopectin. List - II contains carbohydrate linkage descriptions.

Find: The correct matching between List - I and List - II.

From the solution:

• Amylase acts on $\alpha$-C1-C4 glycosidic bonds in plant starch, so (A) \rightarrow (IV).
• Cellulose is a plant polysaccharide with $\beta$-C1-C4 linkages, so (B) \rightarrow (I).
• Glycogen is described in the solution as having $\alpha$-C1-C4 and $\alpha$-C1-C6 linkages, so (C) \rightarrow (III).
• The provided solution concludes Amylopectin \rightarrow (II), so (D) \rightarrow (II).

Therefore, the final matching is $(A)-(IV), (B)-(I), (C)-(III), (D)-(II)$.

The correct option is B.

Note: The solution itself contains a conceptual inconsistency because amylopectin is a plant polysaccharide with $\alpha$-C1-C4$** and **$\alpha$-C1-C6$ linkages, whereas glycogen is the animal storage polysaccharide. However, both the source solution and listed correct option conclude B, so the extracted answer is B.

Given:

1. Amylase is associated with hydrolysis of starch.
2. Cellulose is a plant structural polysaccharide.
3. Glycogen is a storage polysaccharide.
4. Amylopectin is a branched component of starch.

Find: Which option reproduces the matching stated in the solution.

The solution identifies the descriptions as follows:

Comparing this with the options, the arrangement matches:

Hence, the correct option is B.
