WebScore: 4.7/5 (18 votes) . Carbon monoxide is dangerous for several reasons. When CO binds to one of the binding sites on hemoglobin, the increased affinity of the other binding sites for oxygen leads to a left shift of the oxygen dissociation curve and interferes with unloading of oxygen in the tissues.
