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.

The Bohr effect is a phenomenon first described in 1904 by the Danish physiologist Christian Bohr. Hemoglobin's oxygen binding affinity (see oxygen–haemoglobin dissociation curve) is inversely related both to acidity and to the concentration of carbon dioxide. That is, the Bohr effect refers to the shift in the oxygen dissociation curve caused by changes in the concentration of car… WebOne is decreased partial pressure of oxygen at the muscle.

Increased [H +] will cause protonation of basic side chains. In the pH range for the Bohr effect, the mostly likely side chain to get protonated is His (pKa around 6), which then becomes charged.

WebWell, it turns out that not only does CO bind very tightly to hemoglobin in the place oxygen would normally bind, taking up space and reducing the capacity for oxygen, it also very strongly increases the affinity of the other subunits for oxygen.
