Match List I with List II : List I A. Trypsin B. Morphine C. Concanavalin A D. Collagen List II I. Intercellular ground substance II. Lectin III. Enzyme IV. Alkaloid Choose the correct answer from the options given below :
- A.A-III, B-IV, C-II, D-I✓
- B.A-I, B-II, C-III, D-IV
- C.A-IV, B-III, C-II, D-I
- D.A-III, B-II, C-IV, D-I
Correct Answer
(A) A-III, B-IV, C-II, D-I
Solution & Explanation
Answer: (A) A-III, B-IV, C-II, D-I. Solution: Trypsin is listed in NCERT Table 9.5 as an enzyme (A–III). Morphine is an alkaloid, a secondary metabolite in Table 9.3 (B–IV). Concanavalin A is the example given for lectins in Table 9.3 (C–II). Collagen is listed in Table 9.5 as the intercellular ground substance, and the text confirms it is the most abundant protein in the animal world (D–I). This matching uniquely fits option A. NCERT Reference: Ch 9, p.110, line ~27 — "Collagen is the most abundant protein in animal world" (with Table 9.5, p.109: Collagen — Intercellular ground substance, Trypsin — Enzyme)
