# DBT JRF 2022 — Question 12

Exam: DBT JRF 2022 · Section: A · Topic: Biochemistry › Metabolic Pathways - Match the Following · Difficulty: Medium

## Question

Match the items in List I with the items in List II:
| List I (Sugar) | List II (Glycosidic Link) |
| --- | --- |
| (A) Sucrose | I. β-glycosidic link (D-glucose) |
| (B) Lactose | II. α-glycosidic link (D-glucose) |
| (C) Maltose | III. β-glycosidic link (D-glucose and D-galactose) |
| (D) Cellobiose | IV. α-1, β-2-glycosidic link (D-glucose and D-fructose) |
 Choose the correct answer from the options given below:

## Options

- **A.** A-II, B-IV, C-I, D-III
- **B.** A-I, B-III, C-IV, D-II
- **C.** A-III, B-II, C-I, D-IV
- **D.** A-IV, B-III, C-II, D-I

## Answer

Option D

## Explanation

Match the following — biochemical pathways (see question table): The correct matching is A-IV, B-III, C-II, D-I, where each item in List I (A–D) is paired with its corresponding description in List II (I–IV). Note: Without the exact image/table, the explanation relies on the answer key. Students should refer to the actual question image
| List I (Sugar) | List II (Glycosidic Link) |
| --- | --- |
| (A) Sucrose | I. β-glycosidic link (D-glucose) |
| (B) Lactose | II. α-glycosidic link (D-glucose) |
| (C) Maltose | III. β-glycosidic link (D-glucose and D-galactose) |
| (D) Cellobiose | IV. α-1, β-2-glycosidic link (D-glucose and D-fructose) |
 to verify each pairing.
