AThe Haldane effect
BThe Bohr effect
CThe chloride shift
DThe Boyle effect
Answer & Solution
Correct answer: B. The Bohr effect
1. Two named effects sit close together here and are easily swapped.
2. The Bohr effect is the relationship between pH and the affinity of haemoglobin for oxygen.
3. The Haldane effect is the relationship between oxygen partial pressure and the affinity of haemoglobin for carbon dioxide.
4. Since the question asks about pH and oxygen, the answer is the Bohr effect.
