Hemoglobin:

1. Hemoglobin binds carbon monoxide 200-300 times more than oxygen.
2. It results in the formation of carboxyhemoglobin.
3. Hence it prevents the binding of oxygen to hemoglobin.
4. This happens because of competition for the same binding sites.

Final answer: The given statement is true.
