Shift of the oxygen dissociation curve to right is caused by the following factors EXCEPT_______________?
Correct answer: D. Increased concentration of oxygen
- A. Increased 2,3 BPG
- B. Increased temperature
- C. Increased concentration of carbon - di - oxide
- D. Increased concentration of oxygen
Explanation
Raised 2,3-BPG, temperature and carbon dioxide each reduce haemoglobin's oxygen affinity and shift the dissociation curve to the right. A raised oxygen concentration is not a recognised cause of this rightward shift.
