Question

Given below are two statements:
Statement (I): Pancreatic juice contains inactive proteolytic enzymes like trypsinogen and chymotrypsinogen.
Statement (II): The enzyme enterokinase in intestinal juice helps in the conversion of inactive chymotrypsinogen into its active form, chymotrypsin.
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 activates trypsinogen into trypsin, and trypsin then activates chymotrypsinogen.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
Pancreatic juice contains proteases in inactive forms (zymogens) so that the pancreas is not digested by its own enzymes.

Step 2: Statement (I)
Trypsinogen and chymotrypsinogen are inactive proteolytic enzymes present in pancreatic juice. Statement (I) is correct.

Step 3: Statement (II)
Enterokinase of the intestinal juice converts trypsinogen into trypsin. It is trypsin that then activates chymotrypsinogen to chymotrypsin. Statement (II) is incorrect.

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