Which of the following can be termed as opposited of Bohr's effect ?

Options

A. Haldane's effect
B. Hamburger's phenomenon
C. Hering-Breuer refiex
D. None of these

Answer

To determine which of the following can be termed as the opposite of the Bohr's effect, we need to understand the Bohr effect and its implications on hemoglobin's affinity for oxygen and carbon dioxide.

### Step-by-Step Solution:

1. **Understand the Bohr Effect**:
- The Bohr effect describes how hemoglobin's affinity for oxygen decreases in the presence of high concentrations of carbon dioxide (CO2) and lower pH (more acidic conditions). This means that when CO2 levels are high, hemoglobin releases oxygen more readily to the tissues.

2. **Identify the Opposite Effect**:
- The opposite of the Bohr effect would involve a situation where hemoglobin's affinity for oxygen increases. This typically occurs when oxygen concentration is high and the pH is higher (less acidic).

3. **Recognize the Haldane Effect**:
- The Haldane effect states that hemoglobin's ability to carry carbon dioxide is inversely related to its oxygen saturation. When hemoglobin is saturated with oxygen, its affinity for carbon dioxide decreases, which is the opposite of the Bohr effect.

4. **Evaluate the Options**:
- The options given are:
- Haldane effect
- Hamburg's phenomena
- Herring
- Brood
- Reflex
- None of these
- Among these, the Haldane effect is recognized as the opposite of the Bohr effect.

5. **Conclusion**:
- Therefore, the correct answer to the question is the **Haldane effect**.
