Effect of `CO_(2)` concentration on dissociation of oxyhaemoglobin is called

Options

A. Bohr's effect
B. Haldane effect
C. Hamburger effect
D. Root effect

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the effect of carbon dioxide (CO₂) concentration on the dissociation of oxyhemoglobin. This refers to how changes in CO₂ levels influence the ability of hemoglobin to release oxygen.

2. **Identifying the Options**: The options provided are:
- Bohr's effect
- Haldane effect
- Hamburger effect
- Root effect

3. **Analyzing Each Option**:
- **Bohr's Effect**: This effect states that an increase in CO₂ concentration leads to an increase in hydrogen ion concentration (lower pH), which decreases the affinity of hemoglobin for oxygen. This means hemoglobin releases oxygen more readily to the tissues.
- **Haldane Effect**: This effect describes how oxygen binding to hemoglobin facilitates the release of CO₂. It is not directly related to the dissociation of oxyhemoglobin due to CO₂ concentration.
- **Hamburger Effect**: This effect involves the exchange of chloride ions in red blood cells (RBCs) due to changes in CO₂ concentration, but it does not specifically address the dissociation of oxyhemoglobin.
- **Root Effect**: Similar to the Bohr effect, this is observed in fishes and indicates that increased CO₂ concentration decreases the oxygen binding capacity of hemoglobin, but it is not the primary term used for the human physiological response.

4. **Conclusion**: Based on the analysis, the effect of CO₂ concentration on the dissociation of oxyhemoglobin is best described by the **Bohr effect**.

5. **Final Answer**: The correct answer is **Bohr's effect**.
