The stomach has secretory cells called "cheif cells" which secrete pepsinogen which is the inactive zymogen form of pepsin. When pepsinogen enters the highly acidic environment of the interior of the stomach, it is cleaved into its active form, pepsin. Pepsin is a strong degradtive enzyme used in digestion. It must be secreted as an inactive zymogen so as to avoid digesting the cells its produced from. Those, again, are the cheif cells of the stomach. So, you could say that pepsin is produced in the stomach.

Pepsin is a digestive protease released by the chief cells in the stomach that functions to degrade food proteins into peptides.

pepsin has little activity on BAPNA..this substrate releases p-nitroaniline when acted upon by a trypsin -like enzymes that show prefernce for basic amino acids such as arginine. The resultant chromophore ,p-nitroaniline, absorbs maximally at ~ 405-410 nm

In the stomach, by a group of cells called chief or peptic cells.
