Question
Why is a burning charcoal stove in a poorly ventilated room likely to cause death on the inhabitants.
Answer
Limited supply of oxygen: haemoglobin combines with carbon (II) oxide to form carboxyhemoglobin (haemoglobin that has high affinity for carbon (II) oxide to form carboxyhemoglobin) which is stable / does not easily dissociate hence reducing the capacity of haemoglobin to transport oxygen
