Question

Which of the following helps in protein digestion?

• A. Pancreatic juice
• B. Saliva
• C. Bile
• D. Intestinal juice

Answer 1

The correct option is A Pancreatic juice

• The pancreas secretes pancreatic juice. The pancreatic juice contains the following enzymes trypsinogen, chymotrypsinogen, procarboxypeptidases, amylases, lipases and nucleases.
• The proteolytic enzymes of pancreatic juice trypsin, chymotrypsin and carboxypeptidase convert proteins, peptones and proteases into dipeptides in the small intestine. Hence pancreatic juice helps in protein digestion.
• So, the correct answer is 'Pancreatic juice'.
