Chymotrypsinogen is produced by

Options

A. Liver
B. Pancreas
C. Stomach
D. Duodenum

Answer

**Step-by-Step Solution:**

1. **Understanding Chymotrypsinogen**:
- Chymotrypsinogen is a digestive enzyme that plays a crucial role in the breakdown of proteins in the digestive system. It is classified as a protease, which is an enzyme that breaks down proteins into smaller peptides or amino acids.

2. **Analyzing the Options**:
- The question provides four options regarding where chymotrypsinogen is produced:
- A) Liver
- B) Pancreas
- C) Stomach
- D) Duodenum

3. **Evaluating Each Option**:
- **Option A: Liver**: The liver primarily produces bile, which aids in fat digestion, but it does not produce chymotrypsinogen. Therefore, this option can be ruled out.
- **Option C: Stomach**: The stomach produces gastric juices, including hydrochloric acid and pepsinogen (another enzyme), but not chymotrypsinogen. Thus, this option is also incorrect.
- **Option D: Duodenum**: The duodenum is the first part of the small intestine where most chemical digestion occurs, but it does not produce chymotrypsinogen. This option can be eliminated as well.

4. **Identifying the Correct Option**:
- The only remaining option is **Option B: Pancreas**. The pancreas is known to produce several digestive enzymes, including chymotrypsinogen, which is secreted into the small intestine where it is activated to chymotrypsin.

5. **Conclusion**:
- Therefore, the correct answer is that chymotrypsinogen is produced by the **pancreas**.

**Final Answer**: Chymotrypsinogen is produced by the **pancreas**.
