Question

Match the secondary metabolites in Group-I with types of secondary metabolites in Group-II in CORRECT order.

Which one of the following combinations is correct?

• A. P-I, Q-V, R-II, S-IV, T-III
• B. P-V, Q-II, R-IV, S-I, T-III
• C. P-II, Q-III, R-IV, S-V, T-I
• D. P-V, Q-I, R-II, S-IV, T-III

Hint:

Secondary metabolites like alkaloids, flavonoids, and terpenes are crucial for plant defense and other functions. Each type has distinct chemical characteristics and biological roles.

Answer 1

The Correct Option is D

Step 1: Understanding Secondary Metabolites.
Secondary metabolites are organic compounds that are not directly involved in the normal growth, development, or reproduction of organisms. They include a wide variety of chemicals like alkaloids, flavonoids, terpenes, and glycosides.
Step 2: Analyzing the Options.
- (A) P-I, Q-V, R-II, S-IV, T-III: This is incorrect as the matches are not correct.
- (B) P-V, Q-II, R-IV, S-I, T-III: This is incorrect as some metabolites do not match their correct group.
- (C) P-II, Q-III, R-IV, S-V, T-I: This is incorrect. The assignments are mismatched.
- (D) P-V, Q-I, R-II, S-IV, T-III: This is correct. Myrcene is a monoterpene (P-V), β-Farnesene is a sesquiterpene (Q-I), Amygdalin is a cyanogenic glycoside (R-II), Nicotine is an alkaloid (S-IV), and Luteolin is a flavone (T-III).
Step 3: Conclusion.
The correct answer is (D) P-V, Q-I, R-II, S-IV, T-III, as the metabolites are correctly matched with their respective groups.
