Which of the following pancreatic cells produce glucagon ?

Options

A. `beta`-cells
B. `alpha`-cells
C. `gamma`-cells
D. `delta`-cells

Answer

**Step-by-Step Solution:**

1. **Understanding the Pancreas**: The pancreas is a gland in the body that plays a crucial role in digestion and blood sugar regulation. It contains clusters of cells known as the islets of Langerhans.

2. **Identifying the Types of Cells**: Within the islets of Langerhans, there are three main types of cells:
- **Alpha Cells**: These cells are responsible for producing the hormone glucagon.
- **Beta Cells**: These cells produce insulin, which helps lower blood sugar levels.
- **Delta Cells**: These cells produce somatostatin, which regulates the endocrine system and inhibits the secretion of other hormones.

3. **Function of Glucagon**: Glucagon is a hormone that raises blood glucose levels. It does this by promoting the conversion of stored glycogen in the liver back into glucose, which is then released into the bloodstream.

4. **Conclusion**: Based on the information about the pancreatic cells, the correct answer to the question "Which of the following pancreatic cells produce glucagon?" is the **alpha cells**.

**Final Answer**: The pancreatic cells that produce glucagon are the **alpha cells**.
