Which of the following best describes the effect of the Haldane effect on the transport of carbon dioxide in the blood?
- A.Deoxygenation of blood increases its ability to carry carbon dioxide
- B.Oxygenation of blood increases its ability to carry carbon dioxide
- C.Carbon dioxide binding to hemoglobin increases oxygen affinity
- D.Carbon dioxide binding to hemoglobin decreases oxygen affinity
Show correct answer & step-by-step solution
Correct answer: A — Deoxygenation of blood increases its ability to carry carbon dioxide
Solution
- The Haldane effect describes how the oxygenation state of hemoglobin affects transport.
- Deoxygenated hemoglobin acts as a weaker acid and binds more and .
- This facilitates uptake in tissues where oxygen is released.
- Hence the answer is (A).
