Which one of the following hormones inhibits gastric secretion

Options

A. Enterogastrone
B. GIP
C. Both (I) and (2)
D. Enterocrinin

Answer

To determine which hormone inhibits gastric secretion, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Gastric Secretion**: Gastric secretion refers to the digestive juices produced by the stomach, which include hydrochloric acid and digestive enzymes. These secretions are crucial for the digestion of food.

2. **Identify the Hormones in the Options**: The options provided are:
- Enterogastron
- GIP (Gastric Inhibitory Peptide)
- Both 1 and 2
- Enterocrinine

3. **Research the Functions of Each Hormone**:
- **Enterogastron**: This hormone is known to inhibit gastric secretion.
- **GIP (Gastric Inhibitory Peptide)**: As the name suggests, GIP also inhibits gastric secretion.
- **Enterocrinine**: This hormone does not inhibit gastric secretion; rather, it stimulates the secretion of digestive juices.

4. **Analyze the Options**:
- Since both Enterogastron and GIP are known to inhibit gastric secretion, we can conclude that the correct answer is the option that includes both of these hormones.

5. **Select the Correct Answer**: The correct answer is "Both 1 and 2," which corresponds to Enterogastron and GIP.

### Final Answer:
The hormone that inhibits gastric secretion is **Both 1 and 2 (Enterogastron and GIP)**.
