The small intestine is where most chemical digestion takes place. Most of the digestive enzymes in the small intestine are secreted by the pancreas and enter the small intestine via the pancreatic duct. These enzymes enter the small intestine in response to the hormone cholecystokinin, which is produced in response to the presence of nutrients.
The small intestine produces and secretes many enzymes, as it is here where digestion mainly occurs. These enzymes include:The enzymes mentioned above are actually produced by the pancreas. 1  lipase to break down fat molecules into glycerol and fatty acids.2  Carbohydrase-digest carbohydrates into simpler sugars. 3  proteases digest proteins into amino acids.he enzymes mentioned above are actually produced by the pancreas. 1  lipase to break down fat molecules into glycerol and fatty acids. 2  Carbohydrase-digest carbohydrates into simpler sugars. 3  proteases digest proteins into amino acids.
