Question

Match the following enzymes in Column I with their applications in Column II.

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

Hint:

Remember enzymes by product: - \(\beta\)-Glucanase → brewing, - Amylases → bread, - Pectinase → juice, - Papain → meat tenderizer.

Answer 1

The Correct Option is B, C

Step 1: Role of \(\beta\)-Glucanase.
\(\beta\)-Glucanase is used in the brewing industry to break down \(\beta\)-glucans in barley and malt, improving filtration. Hence: P-4 (Brewing).


Step 2: Role of \(\alpha\)- and \(\beta\)-Amylases.
Amylases hydrolyze starch into sugars. In bread making, they provide fermentable sugars for yeast and improve dough quality. Hence: Q-2 (Bread making).


Step 3: Role of Pectinase.
Pectinase breaks down pectin, reducing turbidity in juices, and is widely used in clarification of fruit juices. Hence: R-1 (Fruit juice clarification).


Step 4: Role of Papain.
Papain is a proteolytic enzyme that hydrolyzes proteins and is commonly used for meat tenderization. Hence: S-3 (Meat tenderization).




Step 5: Sequence.
\[ P-4, Q-2, R-1, S-3 \] Final Answer:
\[ \boxed{\text{(B) P-4; Q-2; R-1; S-3}} \]
