In Haldane effect CO2 dissociation curve is shifted to_____________?
Correct answer: B. Right
- A. Left
- B. Right
- C. Does not shift
- D. None of the above
Explanation
In the Haldane effect, oxygenation of haemoglobin in the lungs reduces its ability to carry CO2 and hydrogen ions, promoting CO2 release. Therefore, at a given PCO2, oxygenated blood carries less CO2 and the CO2 dissociation curve shifts to the right.
