Gastric juice of infants contains pepsinogen, lipase and rennin. Gastric juice does not contain amylase, maltase & nuclease.

1. Rennin (also called chymosin) is an enzyme that occurs in gastric juice and is a constituent of rennet.
2. It coagulates milk by converting caseinogen to casein.
3. The initial step in the digestion of milk in humans is carried out by rennin.
4. Facilitated transport is a form of passive transport in which materials are moved across the plasma membrane by a transport protein down their concentration gradient; hence, it does not require energy.

Correct answer: It coagulates milk by converting caseinogen to casein.

Solution

Rennin (chymosin) is a gastric enzyme in infants that curdles milk by converting soluble caseinogen into insoluble casein. That clotting action helps milk stay longer in the stomach for digestion.
