Question

Match List I with List II and choose the correct answer.

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

Hint:

• Protease → Peptides
• Lipase → Fat removal
• Amylase → Sugar syrup
• Phytase → Animal feed

Answer 1

The Correct Option is D

Concept: Different enzymes have specific industrial applications:
• Proteases → Used to generate bioactive peptides
• Lipases → Used in fat breakdown (e.g., degreasing)
• Amylases → Used in starch processing
• Phytases → Used in animal nutrition

Step 1: Matching each enzyme.

• Alkalase: A protease used to produce bioactive peptides → IV
• Lipase: Used in degreasing of leather hides → III
• $\beta$-amylase: Produces maltose-rich syrup → II
• Phytase: Used in animal feed to improve phosphate availability → I

Step 2: Writing the correct combination.
\[ A \rightarrow IV,\quad B \rightarrow III,\quad C \rightarrow II,\quad D \rightarrow I \] Thus, the correct option is (D).
