Match List I with List II:
List-I (Enzymatic reaction): A. Sucrose → Glucose and Fructose B. Glucose → ethyl alcohol and CO₂ C. Starch → Maltose D. Proteins → Amino acids
List-II (Enzyme): I. Zymase II. Pepsin III. Invertase IV. Diastase
Choose the correct answer from the options given below:
  1. (A)A-III, B-I, C-II, D-IV
  2. (B)A-I, B-IV, C-III, D-II
  3. (C)A-III, B-I, C-IV, D-II✓ Correct
  4. (D)A-I, B-II, C-IV, D-III

Answer: (C)

Solution

Each enzyme is matched to the conversion it catalyses. Invertase hydrolyses sucrose into glucose and fructose. Zymase ferments glucose to ethyl alcohol and carbon dioxide. Diastase breaks starch down into maltose. Pepsin digests proteins into amino acids. The correct pairing is sucrose with invertase, glucose with zymase, starch with diastase, and proteins with pepsin.
