Trypsin digests proteins in

Options

A. Stomach in acidic medium
B. Stomach in alkaline medium
C. Intestine in alkaline medium
D. Intestine in acidic medium

Answer

To solve the question "Trypsin digests proteins in," we need to analyze the characteristics of the enzyme trypsin and the conditions under which it operates effectively.

### Step-by-Step Solution:

1. **Identify the Function of Trypsin**:
- Trypsin is a type of enzyme known as a serine protease, which means it is involved in breaking down proteins into smaller peptides or amino acids.

2. **Determine the Site of Action**:
- Trypsin is secreted by the pancreas and acts in the small intestine. It is not active in the stomach.

3. **Understand the pH Requirement**:
- Trypsin functions optimally in an alkaline environment. The ideal pH range for trypsin activity is between 7.5 and 8.0, which is alkaline.

4. **Evaluate the Options**:
- The options provided are:
- A) Stomach in acidic medium
- B) Stomach in alkaline medium
- C) Intestine in alkaline medium
- D) Intestine in acidic medium
- Since trypsin is active in the small intestine and requires an alkaline medium, the correct option is C) Intestine in alkaline medium.

5. **Conclusion**:
- Therefore, trypsin digests proteins in the intestine in an alkaline medium.

### Final Answer:
**Trypsin digests proteins in the intestine in alkaline medium.**
