Why carbon monoxide is poisonous?

Asked by Topperlearning User | 4th Jun, 2014, 01:23: PM

Expert Answer:

Carbon monoxide binds to hemoglobin to form carboxyhemoglobin that is 300 times more stable than the oxygen-hemoglobin complex. In blood when the concentration of carboxyhemoglobin reaches 3-4 percent the oxygen carrying capacity of blood is reduced. This oxygen deficiency results in different disorders.
