CO is more toxic than `CO_(2)` because it `:`

Options

A. it effects the revous system
B. it damages lungs
C. it reduce the oxygen carrying capactiy of haemoglobin
D. it forms acid with water

Answer

**Step-by-Step Solution:**

1. **Understanding the Compounds:**
- Carbon monoxide (CO) and carbon dioxide (CO₂) are both gases that can be found in the environment, but they have different effects on the human body.

2. **Binding Affinity:**
- Carbon monoxide has a much higher binding affinity for hemoglobin compared to carbon dioxide. This means that CO can bind to hemoglobin more readily than CO₂ can.

3. **Impact on Oxygen Transport:**
- Hemoglobin is responsible for transporting oxygen in the blood. When carbon monoxide binds to hemoglobin, it prevents oxygen from binding. This reduces the overall oxygen-carrying capacity of the blood.

4. **Toxicity of Carbon Monoxide:**
- Because CO binds to hemoglobin instead of oxygen, it can lead to hypoxia (a deficiency in the amount of oxygen reaching the tissues), which can be very harmful and potentially fatal.

5. **Conclusion:**
- Therefore, the reason CO is more toxic than CO₂ is that it reduces the oxygen-carrying capacity of hemoglobin, leading to serious health risks.

**Final Answer:**
CO is more toxic than CO₂ because it reduces the oxygen-carrying capacity of hemoglobin.
