Oxygen affinity decreases in_________________?
Correct answer: D. Hypoxia
- A. Increased pH
- B. Hypothermia
- C. HbF
- D. Hypoxia
Explanation
Hypoxia decreases haemoglobin's oxygen affinity mainly through increased 2,3-BPG, shifting the dissociation curve to the right. Hypothermia, HbF and increased pH shift it left and increase affinity.
