What is the effect of carbon monoxide poisoning on hemoglobin's oxygen-binding properties?
A
It increases the affinity of hemoglobin for oxygen
B
It decreases the affinity of hemoglobin for oxygen
C
It has no effect on the affinity of hemoglobin for oxygen
D
It displaces oxygen from hemoglobin, reducing its oxygen-carrying capacity
✓
Explanation
Carbon monoxide poisoning can lead to a reduction in the oxygen-carrying capacity of hemoglobin, as carbon monoxide binds to hemoglobin with high affinity, displacing oxygen.
