Pepsinogen is secreted by

Options

A. Argentaffin cells
B. Goblets cells
C. Chief cells
D. Parietal cells

Answer

**Step-by-Step Solution:**

1. **Understanding Pepsinogen**: Pepsinogen is an enzyme that plays a crucial role in the digestion of proteins. It is the inactive form of the enzyme pepsin.

2. **Identifying the Source of Secretion**: The question asks which cells secrete pepsinogen. We need to analyze the options provided:
- A) Rgen teffin cells
- B) Goblet cells
- C) Chief cells
- D) Parietal cells

3. **Eliminating Incorrect Options**:
- **Rgen teffin cells**: This option seems to be a typographical error or a non-existent cell type in the context of digestion.
- **Goblet cells**: These cells are primarily responsible for secreting mucus in the gastrointestinal tract, not pepsinogen.
- **Parietal cells**: These cells secrete hydrochloric acid (HCl) and intrinsic factor, but they do not secrete pepsinogen.

4. **Identifying the Correct Option**: The only option left is:
- **C) Chief cells**: Chief cells, also known as gastric chief cells, are located in the gastric glands of the stomach and are responsible for secreting pepsinogen.

5. **Conclusion**: Pepsinogen is secreted by chief cells, which convert it into the active enzyme pepsin in the presence of gastric acid.

**Final Answer**: Pepsinogen is secreted by **Chief Cells** (Option C).
