1.	Why is CO considered poisnous ?
Answer» And at last person die due to suffocation............In Addition to Priya\'s Answer.....<br>It binds to haemoglobin to form carboxyhaemoglobin.which is 300 timrs more stable than the oxygen haemoglobin complex. The capacity of oxygen is reduced in blood. This leads to nervesness,headache,weakness,cardivascular disorder......and many more<br>Carbon monoxide (CO) is considered to be more toxic or hazardous than Carbon Dioxide (CO2) due to the fact that CO reacts with the hemoglobin in our blood streams and produces a stable compound that actually prevents oxygen from entering the body. However, CO2 is more tolerable in a human body because we are able to exhale it. And it doesn\'t have the same chemical properties that CO has. CO2 doesn\'t react with the hemoglobin in our blood streams. To be more specific there is a reaction between CO and the hemoglobin in our body that occurs while on the other hand the CO2 doesn\'t. Basically, the hemoglobin is an oxygen binding protein, and CO is more ready to share it\'s oxygen atom with the hemoglobin than the CO2. read less
