Name the nondigestive enzyme which helps in activation of trypsinogen

Answer

**Step-by-Step Solution:**

1. **Identify the Enzyme in Question**: The question asks for a non-digestive enzyme that activates trypsinogen.

2. **Understand Trypsinogen**: Trypsinogen is a precursor (inactive form) of the enzyme trypsin, which is involved in protein digestion. It is secreted by the pancreas into the small intestine.

3. **Activation Process**: Trypsinogen must be activated to become trypsin. This activation is crucial for protein digestion to occur.

4. **Identify the Activating Enzyme**: The enzyme responsible for converting trypsinogen into trypsin is known as enterokinase (also called enteropeptidase).

5. **Source of Enterokinase**: Enterokinase is produced in the small intestine, specifically by the intestinal mucosa.

6. **Conclusion**: Therefore, the non-digestive enzyme that helps in the activation of trypsinogen is enterokinase.

**Final Answer**: Enterokinase
