Question

Match List I with List II 

Choose the correct answer from the options given below: 
 

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

Hint:

Digestive Enzyme Substrates: Amylase = Starch; Lipase = Fats/Lipids; Rennin = Milk Casein; Pepsin = Proteins.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Digestive biochemistry: digestive enzymes and their specific macromolecular dietary substrates.

Step 2: Detailed Explanation:
Matching digestive enzymes in List I with target substrates in List II:
- A. Amylase (Ptyalin Pancreatic $\alpha$-amylase): Hydrolyzes II. Starch into maltose and dextrins.
- B. Lipase (Pancreatic Steapsin): Hydrolyzes IV. Fats (triglycerides) into monoacylglycerols and free fatty acids.
- C. Rennin (Chymosin): Specifically coagulates III. Milk protein ($\kappa$-casein into paracasein) in suckling young.
- D. Pepsin: Gastric endopeptidase that hydrolyzes dietary I. Protein into peptones and peptides.
Matching sequence: A - II, B - IV, C - III, D - I.

Step 3: Final Answer:
Thus, the correct matching is A - II, B - IV, C - III, D - I, corresponding to option (C).
