Biology - Digestion and Absorption Question with Solution | TestHub
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 themost appropriateanswer from the options given below.
Options:
Answer:
Solution:
Statement (I) is correct because pancreatic juice contains inactive proteolytic enzymes such as trypsinogen, chymotrypsinogen, and procarboxypeptidases.
Statement (II) is incorrect because the enzyme enterokinase, secreted by the intestinal mucosa, activates trypsinogen into active trypsin. It is the active trypsin that subsequently activates other inactive enzymes in the pancreatic juice, including the conversion of chymotrypsinogen into chymotrypsin. Enterokinase does not directly convert chymotrypsinogen into chymotrypsin.
Answer: Statement (I) is correct but Statement (II) is incorrect.
