Which of the following options best represents the enzyme composition of pancreatic juice?

  1. Amylase, Pepsin, Trypsinogen, Maltase
  2. Peptidase, Amylase, Pepsin, Rennin
  3. Lipase, Amylase, Trypsinogen, Procarboxypeptidase
  4. Amylase, Peptidase, Trypsinogen, Rennin

Answer

(3) Lipase, Amylase, Trypsinogen, Procarboxypeptidase

Solution

As per NCERT, the pancreatic juice contains inactive enzymes – trypsinogen, chymotrypsinogen, procarboxypeptidases – along with amylases, lipases and nucleases.

Pepsin and rennin are enzymes of the gastric juice, while maltase and peptidases are present in the intestinal juice (succus entericus).

Lipase, amylase, trypsinogen and procarboxypeptidase best represent pancreatic juice.

Answer: (3)
