Explanation:
Hemoglobin is found in the red blood cells and is responsible for the transportation of oxygen from the lungs to the various body cells.
Oxygen binds to hemoglobin because it has a high affinity for it. This aids its transportation. When it gets to the cells it unbinds and get transported into the cell for use in energy production.
Carbon monoxide is an odourless, dangerous gas which has more affinity for hemoglobin than oxygen. Therefore when carbon monoxide is inhaled, it quickly binds to hemoglobin, thereby displacing oxygen. It binds to hemoglobin for a longer period and due to this, the body does not get any oxygen and cells begin to die.
Symptoms of carbon monoxide poisoning include dizziness, headaches, fatigue and coma.
