Trypsin is secreted by-

Options

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

Answer

**Step-by-Step Solution:**

1. **Identify the Enzyme:** The question asks about the secretion of trypsin, which is a digestive enzyme.

2. **Locate the Source:** Trypsin is primarily involved in protein digestion. To determine where it is secreted from, we need to look at the organs involved in digestion.

3. **Understand the Role of the Pancreas:** The pancreas is known for producing pancreatic juice, which contains several digestive enzymes, including trypsin.

4. **Activation of Trypsin:** It is important to note that trypsin is secreted in an inactive form called trypsinogen. This inactive form is not capable of digesting proteins until it is activated.

5. **Activation Mechanism:** Trypsinogen is activated to trypsin in the small intestine by an enzyme called enterokinase. This process is crucial for the digestion of proteins.

6. **Conclusion:** Based on the information, the correct answer to the question "Trypsin is secreted by-" is the pancreas.

**Final Answer:** Trypsin is secreted by the pancreas.
