The enzyme Trypsinogen is activated by Correct Answer enterokinase

The correct option is enterokinase

Concept:

  • The process of digestion is accomplished by mechanical and chemical processes.
  • The digestive glands secrete several enzymes responsible for digesting the ingested food.
  • Digestion of the food starts within the mouth itself where carbohydrates are digested with the help of salivary amylase.
  • The small intestine is the site of the complete digestion of carbohydrates, proteins and fats.
  • It receives the secretions of the liver and pancreas for this purpose.


Explanation:

  • Bile, pancreatic juice and intestinal juice are the secretions released into the small intestine.
  • Pancreatic juice and bile are released through the hepato-pancreatic duct.
  • The pancreatic juice contains inactive enzymes – trypsinogen, chymotrypsinogen, procarboxypeptidases, amylases, lipases and nucleases.
  • Trypsinogen is activated by an enzyme, enterokinase, secreted by the intestinal mucosa into active trypsin, which in turn activates the other enzymes in the pancreatic juice.

Additional Information 

Nucleases-

  • Nucleases in the pancreatic juice act on nucleic acids to form nucleotides and nucleosides.


Trypsin and chymotrypsin -

  • These help in the digestion of Proteins, proteoses and peptones (partially hydrolysed proteins).
