The proteolytie enzyme that acts in alkaline medium is produced from

Options

A. salivary glands
B. gastric glands
C. intestinal glands
D. pancreas

Answer

To solve the question regarding the proteolytic enzyme that acts in an alkaline medium, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Proteolytic Enzymes**:
- Proteolytic enzymes, also known as proteases, are responsible for breaking down proteins into smaller peptides or amino acids.

2. **Identifying the Medium**:
- The question specifies that we are looking for a proteolytic enzyme that operates in an alkaline medium. Alkaline conditions typically have a pH greater than 7.

3. **Sources of Proteolytic Enzymes**:
- We need to consider the options provided:
- A. Salivary glands
- B. Gastric glands
- C. Intestinal glands
- D. Pancreas

4. **Analyzing Each Option**:
- **A. Salivary glands**: Produce salivary amylase, which is not a proteolytic enzyme and works in a neutral pH.
- **B. Gastric glands**: Produce pepsin, which is a proteolytic enzyme but operates in an acidic medium (pH around 1.5 to 3.5).
- **C. Intestinal glands**: Produce enzymes that work in the small intestine, but they are not primarily the source of proteolytic enzymes in alkaline conditions.
- **D. Pancreas**: Produces pancreatic juice, which contains several proteolytic enzymes such as trypsin, chymotrypsin, and carboxypeptidase. These enzymes are activated in the small intestine and function optimally in an alkaline environment (pH around 7.8).

5. **Conclusion**:
- Based on the analysis, the correct answer is **D. Pancreas**. The pancreas produces proteolytic enzymes that act in an alkaline medium.

### Final Answer:
The proteolytic enzyme that acts in an alkaline medium is produced by **D. Pancreas**.
