which of the following enzymes helps in early digestion of milk proteins in infants?

Options

A. Renin
B. trypsin
C. amylopsin
D. lactase

Answer

To solve the question about which enzyme helps in the early digestion of milk proteins in infants, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: Infants primarily rely on breast milk for nutrition, which contains various nutrients, including proteins.

2. **Identify the Key Nutrient**: The question specifically asks about the digestion of milk proteins. Proteins are made up of amino acids linked by peptide bonds.

3. **Know the Enzymes Involved**: In the digestive system, enzymes called proteases are responsible for breaking down proteins into smaller peptides and amino acids.

4. **Focus on Infants**: Infants have a specific enzyme that aids in the digestion of milk proteins. This enzyme is particularly important in the early stages of life when the infant's digestive system is still developing.

5. **Identify the Specific Enzyme**: The enzyme that is crucial for the digestion of milk proteins in infants is called **renin** (also known as chymosin). Renin curdles the milk, making it easier for the infant's stomach to digest the proteins.

6. **Conclusion**: Based on the information gathered, the correct answer to the question is **renin**.

### Final Answer:
The enzyme that helps in the early digestion of milk proteins in infants is **renin**.
