state the major steps contained by the digestion of proteins as the food PASES THRu different parts of alimentary waterway?

mouth
no action
Stomach
Renin act upon Caesin and converts it to Paracaesin
Pepsinogen is acted upon by HCl and gets converted to pepsin
proteins are acted upon by pepsin and get converted to Proteoses + Peptones.
Small in testine
i)Bile - no bustle
ii)Pancreas
trypsinogen is acted upon by enterokinase and gets conv. to trypsin
proteins are acted upon byb trypsin and grasp conv. to proteoses + peptones
chymotrypsinogen is acted upon by trypsin and gets conv. to chymotrypsin
procarboxypeptidase is acted upon by trypsin and get conv. to carboxypepyidase
Proteins and Proteoses and Peptones} all acted upon by Chymotrypsin/Carboxypeptidase(. to the reactant acted upon) and win conv. to Dipeptides.
iii)Dipeptides are acted upon by dipeptidases and get conv. to amino acids
This completes the digestion of proteins contained by the alimentary canal.
In stomach
proteins------->metaproteins(i. da presence of pepsin)
metaproteins--->primary proteoses
pri. proteoses--->sec. proteoses
sec.proteoses--->peptones
In duodenum
peptones---->polypeptides n dipeptides(in da pr. of caboxypeptidase n aminopeptidase)
In ilaeum
polypeptide--->dipeptides(in da pr. ov polypeptidase)
dipeptidase--->amino acids(in da pr. ov dipeptidase)
