How does the concentration of chloride ions affect the oxygen-binding affinity of hemoglobin?
A
Chloride ions increase the oxygen-binding affinity of hemoglobin
B
Chloride ions have no effect on the oxygen-binding affinity of hemoglobin
C
Chloride ions decrease the oxygen-binding affinity of hemoglobin
✓
D
Chloride ions stabilize the deoxy form of hemoglobin
Explanation
Chloride ions can decrease the oxygen-binding affinity of hemoglobin by binding to the protein and stabilizing the deoxy form.
