State the role of pancreatic juice in digestion of proteins.
Answer

Role of pancreatic juice in digestion of proteins.

The pancreatic juice contains inactive enzymes – trypsinogen, chymotrypsinogen, procarboxypeptidases, amylases, lipases and nucleases. 

i. Proteins, proteoses and peptones in the chyme reaching the intestine are acted upon by the proteolytic enzymes of pancreatic juice.
