Question

Match the enzymes in Group I with the corresponding substrate in Group II 
   Group I             Group II 
(P) Amylase      (1) Protein 
(Q) Pepsin         (2) Fat 
(R) Lipase          (3) RNA 
(S) Ribozyme     (4) Starch 
 

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

Hint:

Amylase, pepsin, lipase, and ribozyme each have specific substrates. Amylase acts on starch, pepsin on protein, lipase on fat, and ribozyme on RNA.

Answer 1

The Correct Option is B

To solve the given question, we need to match each enzyme in Group I with its corresponding substrate in Group II. Let's examine each enzyme:

1. Amylase: Amylase is an enzyme that catalyzes the hydrolysis of starch into sugars. Therefore, the appropriate match for amylase is starch.
2. Pepsin: Pepsin is a digestive protease enzyme that breaks down proteins into peptides. Thus, pepsin should match with protein.
3. Lipase: Lipase is an enzyme that catalyzes the breakdown of fats into glycerol and fatty acids. Hence, the correct substrate for lipase is fat.
4. Ribozyme: Ribozymes are RNA molecules that catalyze specific biochemical reactions, similar to the action of protein enzymes. They specifically act on RNA substrates.

Now, matching these findings to each group, we get:

• P (Amylase) - 4 (Starch)
• Q (Pepsin) - 1 (Protein)
• R (Lipase) - 2 (Fat)
• S (Ribozyme) - 3 (RNA)

From the given options, the correct answer is:

P-4, Q-1, R-2, S-3
