Question
Renin (in infants) acts on which substrate in the stomach?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Renin (also called chymosin) acts on milk protein (casein) to produce curdled milk (solid casein). This slows gastric emptying, allowing more time for protein digestion in infants who consume milk as their primary food.
Hint
This enzyme coagulates milk, forming solid curds that digest more slowly.
