Question

Match the entries in Group I with those in Group II
Group I
P) Phytase
Q) Xylanase
R) Laccase
S) Bromelain
Group II
1) paper and pulp processing
2) delignification
3) gluten complex reduction
4) improve mineral availability
5) phosphorylation

• A. P-4, Q-1, R-3, S-5
• B. P-4, Q-1, R-2, S-3
• C. P-5, Q-4, R-5, S-2
• D. P-5, Q-1, R-2, S-3

Hint:

Enzyme applications often relate to their substrate: xylanase → xylan in pulp, laccase → lignin removal.

Answer 1

The Correct Option is B

Step 1: Match each enzyme with its application.
Phytase → improves mineral availability (4).
Xylanase → used in paper and pulp processing (1).
Laccase → involved in delignification (2).
Bromelain → helps reduce gluten complexes (3).
Step 2: Compare with options.
This matches option (B): P-4, Q-1, R-2, S-3.
Step 3: Conclusion.
Thus, option (B) gives the correct matching.
