Release of pancreatic juice is stimulated by

Options

A. Enterokinase
B. Cholecystokinin
C. Trypsinogen
D. Secretin

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which substance stimulates the release of pancreatic juice. Pancreatic juice is essential for digestion and contains various enzymes.

2. **Analyzing the Options**:
- **Enterokinase**: This is an enzyme that activates trypsinogen (a pro-enzyme) into trypsin. However, it does not stimulate the release of pancreatic juice itself.
- **Cholecystokinin (CCK)**: This is a hormone that plays a significant role in digestion. It stimulates the gallbladder to release bile and the pancreas to secrete pancreatic juice.
- **Trypsinogen**: This is a pro-enzyme present in pancreatic juice. It is not a stimulant for the release of pancreatic juice.
- **Secretin**: This hormone primarily stimulates the pancreas to secrete bicarbonate and water, rather than the digestive enzymes in pancreatic juice.

3. **Identifying the Correct Answer**: Among the options, Cholecystokinin (CCK) is the hormone that stimulates the pancreas to release pancreatic juice. Therefore, the correct answer is **Cholecystokinin**.

4. **Conclusion**: The release of pancreatic juice is primarily stimulated by the hormone **Cholecystokinin (CCK)**.
