Q.5:- Describe the process of digestion of protein in stomach.

 

Answer

The food that enters the stomach becomes acidic on mixing with this gastric juice which is secreted by gastric glands present on the wall of stomach. The main components of gastric juice are hydrochloric acid, pepsinogen, mucus, and rennin. The inactive proenzyme, pepsinogen when acted upon by hydrochloric acid gets converted into active enzyme pepsin which coverts protein into proteoses and peptides.



Renin which is present in gastric juice of infants helps in the digestion of milk protein.
