Explanation

• Rennin (also known as Chymosin) is an enzyme produced in the stomach of ruminant mammals, such as cows, and is also present in the gastric juice of humans.
• It helps to coagulate milk by converting casein, a milk protein, into a gel-like substance, causing the milk to curdle.
• This process helps to slow down the digestion of milk and allows for better absorption of nutrients.
