Name the compound formed by haemoglobin with carbon dioxide.

Answer

To answer the question about the compound formed by hemoglobin with carbon dioxide, follow these steps:

### Step-by-Step Solution:

1. **Understanding Hemoglobin**:
- Hemoglobin is a protein found in red blood cells that is responsible for transporting gases, primarily oxygen and carbon dioxide.

2. **Interaction with Oxygen**:
- When hemoglobin binds with oxygen, it forms a compound called oxyhemoglobin. This is important for delivering oxygen to tissues.

3. **Interaction with Carbon Dioxide**:
- When hemoglobin interacts with carbon dioxide, it forms a different compound.

4. **Identifying the Compound**:
- The specific compound formed when hemoglobin binds with carbon dioxide is known as carbaminohemoglobin.

5. **Function of Carbaminohemoglobin**:
- Carbaminohemoglobin carries carbon dioxide from the tissues back to the lungs, where it is released and exhaled.

### Final Answer:
The compound formed by hemoglobin with carbon dioxide is called **carbaminohemoglobin**.
