Question

Match List I with List II :

List I                  List II
A. Trypsin              I. Intercellular ground substance
B. Morphine             II. Lectin
C. Concanavalin A       III. Enzyme
D. Collagen             IV. Alkaloid

Choose the correct answer from the options given below :

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

Hint:

The "Secondary Metabolites" table in NCERT is extremely high-yield. Memorize: Alkaloids = Morphine/Codeine; Lectins = Concanavalin A.

Answer 1

The Correct Option is A

Step 1 : Understanding the Question
Match chemical substances with their functional categories.
Step 2 : Key Formulas and approach
Identify digestive catalysts, plant alkaloids, structural proteins, and carbohydrate binders.
Step 3 : Detailed Explanation

Trypsin (A): A digestive (A) enzyme. (A-III).

Morphine (B): A secondary metabolite classified as an (B) alkaloid. (B-IV).

Concanavalin A (C): A sugar-binding (C) lectin. (C-II).

Collagen (D): A structural (D) ground substance. (D-I).

Step 4 : Final Answer
Correct match is A-III, B-IV, C-II, D-I. Option (A) is correct.
