Carbon monoxide is a colourless, odourless gas. It is produced whenever carbon-based fuels (coal, gas, wood, charcoal) burn in an atmosphere with a restricted oxygen supply. Thus, when carbon monoxide is inhaled, it enters the bloodstream, binds to hemoglobin, and crowds out the oxygen molecules, thus depriving the cells of the oxygen needed to maintain their vitality. Moreover, the iron atoms which are embedded in the hemoglobin molecule (and which normally bind oxygen to the hemoglobin) will hold onto any residual oxygen more tightly if carbon monoxide is present — resulting in even less oxygen being delivered to the cells and tissue. The cells die, and, for the brain, the cells cannot regenerate.It has been identified that carbon monoxide binds to hemoglobin at the same site as oxygen and forms carboxyhemoglobin. So based on your knowledge of competitive and non competitive inhibitors, determine the type of inhibition by carbon monoxide on hemoglobin :
