The omnipresent colorless and odorless carbon monoxide (CO), generated by combustion, is the leading cause of unintentional death worldwide. CO binds to hemoglobin with affinity more than 200 times greater than oxygen and forms carboxyhemoglobin (COHb). The toxicity of CO is primarily attributable ...
It thus prevents the hemoglobin from taking up oxygen, thereby depriving the body of the oxygen needed for metabolic respiration. The affinity of carbon monoxide for hemoglobin is about 300 times the affinity of oxygen for hemoglobin. The inhalation of concentrations as low as 0.04 percent will ...
Carbon monoxide (CO) is a colorless, odorless, tasteless, and nonirritating gas produced by the incomplete combustion of any carbon-containing material. Common sources of human exposure include smoke inhalation in fires; automobile exhaust fumes; faulty or poorly ventilated charcoal, kerosene, or gas...
Carbon monoxide has more affinity to hemoglobin compared to oxygen. Is the statement true or false?Carbon monoxideCarbon monoxide is abbreviated as CO. It tends to demonstrate destructive effects when breathed because it relocates oxygen in the blood and divests the hea...
Carbon monoxideis a nonirritant gas that competitively and reversibly binds to hemoglobin at the same sites as oxygen but with an affinity that is 230 to 270 times greater and results in marked anemichypoxia.2,3It is produced by incomplete combustion of carbon-containing materials and is therefor...
Because the affinity of Carbon Monoxide for hemoglobin is over 200 times greater than oxygen, Carbon Monoxide binds to hemoglobin evenwhen Carbon Monoxide is at very low partial pressures. With Carbon Monoxide attached, hemoglobin can no longer transport oxygen, rendering the hemoglobin useless until ...

Carbon monoxide comobines with Hb far more readily than O(2) (CO has about 200 times greater affinity for Hb as compared to O(2)), forming a relativelly stable compound carboxyhaemoglobin. This cause low supply of O(2) to the body cells leading to headac
Answer to: Carbon monoxide has a much higher affinity for hemoglobin than does oxygen. Why does this make exposure to carbon dioxide so dangerous?...
Carbon monoxide binds very strongly to the iron atoms in hemoglobin, the principal oxygen-carrying compound in blood. The affinity between CO and hemoglobin is 200 times stronger than the affinity between hemoglobin and oxygen. When CO binds to the hemoglobin it cannot be released nearly as readil...
