Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): Red colour of tomato is due to pigment lycopene.
Reason (R): Papain enzyme is extracted from papaya.

• A. Both (A) and (R) are true and (R) is the correct explation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

Lycopene is a lipid-soluble red carotenoid pigment, while papain is a water-soluble plant protease. Always verify if the Reason explains the "why" of the Assertion to identify unrelated statements.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
This question evaluates two independent biochemical facts related to plant pigments and enzymes.
Lycopene is a carotenoid pigment responsible for red coloration in certain fruits, while papain is a proteolytic enzyme extracted from the latex of papaya.

Step 2: Detailed Explation:
Let us alyze both statements independently:
- Assertion (A): Lycopene is an acyclic isomer of beta-carotene and a powerful antioxidant.
It is synthesized during tomato ripening, accumulating in the chromoplasts and giving the ripe tomato its characteristic bright red color.
Thus, Assertion (A) is chemically and botanically true.
- Reason (R): Papain is a cysteine protease enzyme extracted from the latex of unripe green papaya fruit (*Carica papaya*).
It is used in food processing for meat tenderization, beer clarifying, and digestive aids.
Thus, Reason (R) is biochemically true.
- Relationship: Both Assertion (A) and Reason (R) are correct scientific facts.
However, the extraction of papain from papaya has no biochemical or causal relationship with the red color of tomato.
Therefore, Reason (R) is not the correct explation for Assertion (A).

Step 3: Fil Answer:
Both statements are true, but the Reason is not related to the Assertion.
Hence, the correct option is (B).
