IN WHICH REPLICATION IF DNA TAKES PLACE OR THAT OF HISTONE PROTEIN ALSO
THAT'S WHY FORMATION OF RNA AND PROTEIN TAKES PLACE.
In stomach- Digestion of protein starts in stomach with the help of enzyme pepsin. Pepsin is secreted in inactive form pepsinogen by the chief cells present in stomach. Hydrochloric acid secreted by parietal cell in stomach activates pepsinogen into pepsin.
Pepsin then hydrolysed the protein molecules and converts them into proteoses, peptones and larger peptides.
Then the food moves into small intestine where protein digestion remains continued.
In small intestine, pancreatic juice contains inactive proteases named as chymotrypsinogen, trypsinogen and procarboxypeptidase.
Trypsinogen in small intestine is activated into trypsin by the action of enterokinase (found in the lining of small intestine). Activated trypsin then converts chymotrypsinogen into chymotrypsin and procarboxypeptidase into carboxypeptidase.
Activated chymotrypsin then hydrolyse the proteones and larger peptides into smaller peptides such as dipeptides and tripeptides. Whereas carboxyppetidase hydrolyse the peptide chains from their carboxyl ends and converts them into amino acids.
The dipeptides and tripeptides are breakdown into amino acids with the help of enzymes dipeptidases and tripeptidases secreted in the intestinal juice.
Finally, the digested proteins enter into larger intestine for absorption.
