Enzyme responsible for digestion of protein is

Options

A. ptylin
B. pepsin
C. amylopsin
D. steapsin

Answer

To answer the question about the enzyme responsible for the digestion of protein, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Enzymes**: Enzymes are biological catalysts that speed up chemical reactions in the body, including the digestion of food.

2. **Identifying Types of Digestion**: Digestion involves breaking down macromolecules such as proteins, carbohydrates, and fats into simpler molecules that can be absorbed by the body.

3. **Focusing on Protein Digestion**: The question specifically asks about the digestion of proteins. Proteins are large molecules made up of amino acids.

4. **Identifying the Enzymes Involved**:
- The primary enzyme responsible for protein digestion in the stomach is **Pepsin**.
- Pepsin is secreted by the stomach lining in an inactive form called pepsinogen, which is activated by the acidic environment of the stomach.

5. **Function of Pepsin**: Pepsin breaks down proteins into smaller peptides and peptones, making it easier for the body to absorb amino acids later in the digestive process.

6. **Conclusion**: Therefore, the enzyme responsible for the digestion of proteins is **Pepsin**.

### Final Answer:
The enzyme responsible for the digestion of protein is **Pepsin**.
