Oxygen dissociation cure is shifted to the right in all except_____________?
Correct answer: C. HbF
- A. Fall in pH
- B. Rise in temperature
- C. HbF
- D. Increase of 2, 3 3 DPG
Explanation
A fall in pH, increased temperature and increased 2,3-DPG reduce haemoglobin’s oxygen affinity and shift the dissociation curve rightward. HbF binds 2,3-DPG poorly, giving it higher oxygen affinity and shifting its curve to the left.

The more specific you are, the faster it gets fixed. A source beats an opinion.
