 
 <translate> I got a question for you: Pepsin is an endopeptidase that breaks down proteins into smaller peptides (that is, a protease). 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. Pepsin has a three dimensional structure, of which one or more polypeptide chains twist and fold, bringing together a small number of amino acids to form the active site, or the location on the enzyme where the substrate binds and the reaction takes place. Pepsin is an aspartic protease, using a catalytic aspartate in its active site.

Answer this question: where is pepsin secreted in the digestive system?
Let's think first: <ibo> Enwere m ajụjụ maka gị: Pepsin bụ endopeptidase nke na-agbaji protein n'ime obere peptides (ya bụ, protease). A na-emepụta ya n'ime afọ ma bụrụ otu n'ime isi enzymes na-agbari nri n'ime usoro nri nke ụmụ mmadụ na ọtụtụ anụmanụ ndị ọzọ, ebe ọ na-enyere aka ịgbari protein ndị dị n'ime nri. Pepsin nwere ihe owuwu nwere akụkụ atọ, nke otu ma ọ bụ karịa agbụ polypeptide na-agbagọ ma na-agbagọ, na-eweta ọnụ ọgụgụ dị nta nke amino acids iji mepụta ebe na-arụ ọrụ, ma ọ bụ ebe dị na enzyme ebe substrate na-ejikọ ma mmeghachi omume ahụ na-ewere ọnọdụ. Pepsin bụ aspartic protease, na-eji catalytic aspartate na ebe ya na-arụ ọrụ.  Zaa ajụjụ a: Ebee ka a na-ewepụta pepsin n'ime usoro mgbari nri? Ka anyị buru ụzọ chee echiche:
