The trypsin enzyme is secreted by

Options

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

Answer

**Step-by-Step Solution:**

1. **Identify the Enzyme**: The question asks about the secretion of the trypsin enzyme.

2. **Understand the Function of Trypsin**: Trypsin is a digestive enzyme that plays a crucial role in breaking down proteins into smaller peptides in the digestive system.

3. **Locate the Source of Trypsin**: The pancreas is the organ responsible for producing and secreting trypsin. It releases trypsin in an inactive form known as trypsinogen.

4. **Activation of Trypsin**: Once trypsinogen is secreted by the pancreas, it travels to the duodenum (the first part of the small intestine) where it is activated into trypsin.

5. **Eliminate Incorrect Options**:
- **Duodenum**: This is not correct because the duodenum does not secrete trypsin; it is where trypsin acts on proteins.
- **Liver**: The liver produces bile, not trypsin, so this option is incorrect.
- **Stomach**: The stomach secretes different substances, such as hydrochloric acid and pepsin, but not trypsin.

6. **Conclusion**: The correct answer is that trypsin is secreted by the **pancreas**.

**Final Answer**: The trypsin enzyme is secreted by the pancreas.
