Due to limited oxygen, haemoglobin combines with carbon (II) oxide to formcarboxyhaemoglobin;
Carboxyhaemoglobin does not readily dissociate hence reduces the capacity of haemoglobin to transport oxygen; Carbon (II) oxide is therefore a respiratory poison if breathed in for a longtime;
OR
Explain why burning charcoal in a poorly ventilated room causes death.
Combustion of charcoal uses oxygen and produces carbon (IV)oxide;carbon monoxide breathed in has a higher affinity for haemoglobin than oxygen/carbon monoxide forms a stable compound with haemoglobin;death due to lack of oxygen as no haemoglobin is available to transport oxygen to tissues.
