Question
Which of the following has a stronger affinity for hemoglobin than oxygen has?
Solution
The molecule that has a stronger affinity for hemoglobin than oxygen is carbon monoxide. This is because carbon monoxide can bind to the same site on the hemoglobin molecule that oxygen does, but it binds more tightly, preventing oxygen from being able to bind. This is why carbon monoxide poisoning can be so dangerous - it prevents oxygen from being carried around the body in the blood.
