Zymogen cells of grastric glands produce

Options

A. Chymotrypsin
B. Pepsin
C. Pepsinogen
D. Trypsin

Answer

**Step-by-Step Solution:**

1. **Identify the Cells in Question**: The question refers to "zymogen cells" of gastric glands. These are specialized cells found in the stomach.

2. **Understand the Function of Zymogen Cells**: Zymogen cells, also known as gastric chief cells, are responsible for producing digestive enzymes in their inactive forms, known as zymogens.

3. **Identify the Specific Zymogen Produced**: Among the options provided (Chymotrypsin, Pepsin, Pepsinogen, Trypsin), we need to determine which one is produced by zymogen cells in the gastric glands.

4. **Recognize the Correct Zymogen**: The correct answer is Pepsinogen. This is the inactive form of the enzyme pepsin, which is activated in the acidic environment of the stomach.

5. **Eliminate Incorrect Options**:
- Chymotrypsin and Trypsin are produced in the pancreas, not the gastric glands.
- Pepsin is the active form of the enzyme, while Pepsinogen is the inactive precursor produced by the zymogen cells.

6. **Conclude the Answer**: Therefore, the zymogen cells of gastric glands produce Pepsinogen (Option C).

**Final Answer**: C. Pepsinogen
