Question

Given below are two statements:
Statement (I): Enzyme enterokinase is present in pancreatic juice.
Statement (II): Enterokinase helps in the conversion of inactive trypsinogen into active trypsin.
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:

Enterokinase comes from the intestinal glands, not from the pancreas. It converts inactive trypsinogen into active trypsin.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
Pancreatic juice contains inactive proenzymes such as trypsinogen. They are activated only after reaching the duodenum.

Step 2: Check Statement (I)
Enterokinase (enteropeptidase) is secreted by the intestinal mucosa in the succus entericus, not present in pancreatic juice.
Statement (I) is incorrect.

Step 3: Check Statement (II)
Enterokinase changes trypsinogen into active trypsin, which then activates the other proenzymes.
Statement (II) is correct.

Step 4: Conclusion
Statement (I) is incorrect but Statement (II) is correct.

Final Answer:
Statement (I) is incorrect but Statement (II) is correct. \[ \boxed{\text{(D) }\text{Statement (I) is incorrect but Statement (II) is correct.}} \]
