उत्तर
Rennin is produced by the stomach in an inactive form, called prorennin. After milk is consumed, the gastric acids present in stomach activate the inactive prorennin to active rennin which acts upon casein and converts it into paracasein. Paracasein with the help of calcium ions form Calcium Paracasinate or forms coagulated milk. This coagulated milk turns into peptones in the presence of pepsin.
If milk were not coagulated, it would rapidly flow through the stomach and the digestion of proteins will not take place.
