Answer:
It increases haemoglobin's affinity.
Explanation:
When CO binds to one heme molecule, the haemoglobin molecule becomes in a relaxed state and oxygen can bind so very easily.
The problem is not in the uptake of oxygen, it's with its delivery. The affinity for oxygen increases so much such that it becomes impossible to release and deliver the oxygen to tissues.
