Question

As per Bohr effect:

• A. Increase in pH adds proton, this stimulates hemoglobin to bind more oxygen
• B. Increase in pH removes proton, this stimulates hemoglobin to bind less oxygen
• C. Increase in pH removes proton, this stimulates hemoglobin to bind more oxygen
• D. Decrease in pH removes proton, this stimulates hemoglobin to bind more oxygen

Hint:

Bohr effect:
High pH \(\rightarrow\) more O\(_2\) binding.
Low pH \(\rightarrow\) less O\(_2\) binding (O\(_2\) release).
Facilitates oxygen delivery to tissues.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Bohr effect describes the effect of pH on hemoglobin's oxygen binding.
It is a key physiological phenomenon.

Step 2: Key Formula or Approach:
No specific formula.
Need to understand the Bohr effect.

Step 3: Detailed Explanation:
The Bohr effect states that:
- Increase in pH (decrease in H\(^+\) concentration) removes protons.
- This stimulates hemoglobin to bind more oxygen.
- Decrease in pH (increase in H\(^+\)) promotes oxygen release.
Thus, increase in pH removes proton, stimulates more oxygen binding.

Step 4: Final Answer:
As per Bohr effect, increase in pH removes proton and stimulates hemoglobin to bind more oxygen.
Hence, the correct option is (C).
