Digestion of proteins is affected in the stomach if these cells are removed

Options

A. chief cells
B. neck cells
C. goblet cells
D. acinar cells

Answer

To solve the question regarding which cells' removal would affect protein digestion in the stomach, let's analyze the options step by step.

### Step-by-Step Solution:

1. **Understanding the Role of Stomach Cells**:
- The stomach contains several types of cells, each with specific functions that contribute to digestion. The main types of cells involved in protein digestion are parietal cells and chief cells.

2. **Identifying the Options**:
- A. Chief cells
- B. Neck cells
- C. Goblet cells
- D. SNR cells

3. **Analyzing Each Cell Type**:
- **Chief Cells**: These cells secrete pepsinogen, an inactive enzyme that is converted into pepsin in the presence of hydrochloric acid (HCl). Pepsin is crucial for protein digestion.
- **Neck Cells**: These cells secrete mucus that protects the stomach lining from the acidic environment but do not directly contribute to protein digestion.
- **Goblet Cells**: These cells are primarily found in the intestines and secrete mucus to protect the intestinal lining. They are not involved in stomach protein digestion.
- **SNR Cells**: These are exocrine cells found in the pancreas that produce digestive enzymes. They are not located in the stomach and do not directly affect stomach digestion.

4. **Conclusion**:
- The removal of **Chief Cells** would directly impact the production of pepsin, which is essential for protein digestion in the stomach. Therefore, the correct answer is **A. Chief cells**.

### Final Answer:
**A. Chief cells**
