Match List I with List II

LIST I
Enzymatic reaction		 LIST II
Enzyme
A. Sucrose →\to→ Glocuse and Fructose I. Zymase
B. Glucose →\to→ ethyl alcohol and CO 2_22​ II. Pepsin
C. Starch →\to→ Maltose III. Invertase
D. Proteins →\to→ Amino acids IV. Diastase

Choose the correct answer from the options given below:

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

Correct answer: B

  1. We match each reaction with the correct enzyme:

    A. Sucrose→Glucose + Fructose\text{Sucrose} \to \text{Glucose + Fructose}Sucrose→Glucose + Fructose
    This hydrolysis is catalyzed by invertase.
    So, A→IIIA \to IIIA→III.

    B. Glucose→ethyl alcohol+CO2\text{Glucose} \to \text{ethyl alcohol} + CO_2Glucose→ethyl alcohol+CO2​
    This is alcoholic fermentation, catalyzed by zymase.
    So, B→IB \to IB→I.

    C. Starch→Maltose\text{Starch} \to \text{Maltose}Starch→Maltose
    This conversion is brought about by diastase.
    So, C→IVC \to IVC→IV.

    D. Proteins→Amino acids\text{Proteins} \to \text{Amino acids}Proteins→Amino acids
    Among the given options, the proteolytic enzyme is pepsin.
    So, D→IID \to IID→II.

  2. Therefore, the correct matching is:

A−III,  B−I,  C−IV,  D−IIA-III,\; B-I,\; C-IV,\; D-IIA−III,B−I,C−IV,D−II

  1. Now compare with the options:
  • Option A: A−III,B−I,C−II,D−IVA-III, B-I, C-II, D-IVA−III,B−I,C−II,D−IV ✗
  • Option B: A−III,B−I,C−IV,D−IIA-III, B-I, C-IV, D-IIA−III,B−I,C−IV,D−II ✓
  • Option C: A−I,B−IV,C−III,D−IIA-I, B-IV, C-III, D-IIA−I,B−IV,C−III,D−II ✗
  • Option D: A−I,B−II,C−IV,D−IIIA-I, B-II, C-IV, D-IIIA−I,B−II,C−IV,D−III ✗

Hence, the correct answer is Option B.
