Digestion
digestivedigestdigested
Digestive enzymes are found in the digestive tracts of animals (including humans) and in the tracts of carnivorous plants, where they aid in the digestion of food, as well as inside cells, especially in their lysosomes, where they function to maintain cellular survival.
The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes.

Small intestine

Many of the digestive enzymes that act in the small intestine are secreted by the pancreas and liver and enter the small intestine via the pancreatic duct.






Pancreas

This juice contains bicarbonate, which neutralizes acid entering the duodenum from the stomach; and digestive enzymes, which break down carbohydrates, proteins, and fats in food entering the duodenum from the stomach.









Pepsin

It is produced in the stomach and is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food.

Stomach
gastriccardiafundus
It secretes digestive enzymes and gastric acid to aid in food digestion.








Pancreatic lipase family
pancreatic lipasePNLIPhuman pancreatic lipase
As the primary lipase enzyme that hydrolyzes (breaks down) dietary fat molecules in the human digestive system, it is one of the main digestive enzymes, converting triglyceride substrates like 1 found in ingested oils to monoglycerides 3 and free fatty acids 2a and 2b.
Cholecystokinin
CCKpancreozymincholecystokinin (CCK)
Its presence causes the release of digestive enzymes and bile from the pancreas and gallbladder, respectively, and also acts as a hunger suppressant.
Chyme
Chymuschyme digestivegastric chyme
Chyme results from the mechanical and chemical breakdown of a bolus and consists of partially digested food, water, hydrochloric acid, and various digestive enzymes.
Trypsinogen
Trypsinogen (EC 3.4.23.18/20/21/23/24/26) is the precursor form or zymogen of trypsin, a digestive enzyme.
Chymotrypsinogen
Chymotrypsinogen is an inactive precursor (zymogen) of chymotrypsin, a digestive enzyme which breaks proteins down into smaller peptides.

Enteric nervous system
neurogastroenterologyentericenteric nervous plexus
Secretion by the previous cells is controlled by the enteric nervous system.
The secretion of gastrointestinal enzymes, such as gastrin and secretin, is regulated through cholinergic neurons residing in the walls of the digestive tract.



Zymogen

Fungi also secrete digestive enzymes into the environment as zymogens.
Hydrochloric acid

Its low pH denatures proteins and thereby makes them susceptible to degradation by digestive enzymes such as pepsin.

Ampulla of Vater

The pancreatic duct delivers substances such as bicarbonate and digestive enzymes to the duodenum.
