Amylase produced by
Mouth and Pancreas
Amylase activity
in mouth and duodenum
Amylase
Breaks down starches
Zymogen form of Pepsin
Pepsinogen
Pepsin produced by
Stomach chief cells
Pepsin activity
in stomach (optimal pH = 2)
Pepsin
Breaks down food proteins into peptides
Zymogen form of Trypsin
Tyrpsinogen
Trypsin produced by
Pancreatic acinar cells
Trypsin activity
in duodenum

Non-Enzyme: Bile
Emulsifies fat
Bile produced by
Liver; Stored in Gall Bladder
Bile activity
in Duodenum
Non-Enzyme: Cholecystokinin (CCK, peptide hormone)
Slows gastric emptying; stimulates bile production; suppresses hunger
