Question

Given below are two statements:
Statement (I): Trypsinogen is produced by the pancreas which acts as a digestive enzyme.
Statement (II): Trypsinogen when converted to trypsin by enterokinase, helps in the digestion of fats.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Trypsin is a protease (protein-digesting enzyme), whereas fats are digested by lipases.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Trypsinogen is an inactive enzyme precursor (zymogen) synthesized and secreted by the exocrine pancreas to prevent self-digestion of pancreatic tissues.

Step 2: Detailed Explanation:
- Statement (I): Trypsinogen is produced by the pancreas and released into the small intestine, where it is later activated to assist in digestion. Thus, Statement (I) is correct.
- Statement (II): In the duodenum, the enzyme enterokinase cleaves trypsinogen to convert it into active trypsin. Once active, trypsin functions as a proteolytic enzyme (protease) that hydrolyzes proteins, not fats. Fat digestion is instead driven by pancreatic lipases. Thus, Statement (II) is incorrect.

Step 3: Final Answer:
Statement (I) is correct, but Statement (II) is incorrect.
