Incorrect one of the following is

Options

A. Parietal cells - HCI
B. Peptic cells - pepsinogen
C. Neck cells - mucus
D. Chief cels - intrinsic factor

Answer

To solve the question of identifying the incorrect match among the given options related to the secretion of gastric cells, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Functions of Gastric Cells**:
- **Parietal Cells**: These cells are responsible for secreting hydrochloric acid (HCl), which is essential for digestion in the stomach.
- **Peptic Cells (Chief Cells)**: These cells secrete pepsinogen, which is the inactive form of the enzyme pepsin. Pepsinogen is activated to pepsin in the presence of HCl.
- **Neck Cells**: These cells secrete mucus, which protects the stomach lining from the acidic environment created by HCl.
- **Intrinsic Factor**: This is a glycoprotein necessary for the absorption of vitamin B12, and it is secreted by parietal cells, not chief cells.

2. **Match Each Cell Type with Its Function**:
- **Parietal Cells → HCl**: Correct
- **Peptic Cells → Pepsinogen**: Correct
- **Neck Cells → Mucus**: Correct
- **Chief Cells → Intrinsic Factor**: Incorrect (Chief cells secrete pepsinogen, not intrinsic factor)

3. **Conclusion**:
- The incorrect match is the last one: Chief Cells → Intrinsic Factor. The intrinsic factor is actually secreted by Parietal Cells.

### Final Answer:
The incorrect match is: **Chief Cells → Intrinsic Factor**.
