Answer :
Trypsinogen is the main inactive pro-enzyme found in pancreatic juice. It is activated into trypsin by the enzyme enterokinase, found in the small intestine, and then helps in the digestion process. The inactivity of trypsinogen is crucial as it prevents the digestion of proteins in the pancreas itself, which can lead to pancreatitis.
The inactive pro-enzyme in the pancreatic juice is called trypsinogen. This enzyme is a vital part of the digestive process and is released by the pancreas into the small intestine. When trypsinogen is released, it doesn't immediately begin to break down proteins; rather it remains inactive until it comes into contact with the enzyme enterokinase, which is found along the wall of the small intestine. Enterokinase activates trypsinogen, converting it into its active form, trypsin, which then aids in digestion by breaking down protein molecules.
The reason for having trypsin in an inactive form (trypsinogen) in the pancreatic juice is to prevent the enzyme from digesting proteins within the pancreas itself. If this were to occur, it could cause a condition known as pancreatitis.
So, trypsinogen is the main inactive pro-enzyme in the pancreatic juice, which plays an essential role in the process of digestion once activated by enterokinase, preventing any potential damage to the pancreas.
