Carbon monoxide is poisonous to human beings because
- A it binds 300 times more strongly to haemoglobin than oxygen.
- B it doesn't bind to haemoglobin
- C it forms cyanide in body.
- D it leads to coagulation of blood.
Answer & Solution
Correct Answer
(A) it binds 300 times more strongly to haemoglobin than oxygen.
Step-by-step Solution
Detailed explanation
Carbon monoxide (\(CO\)) has a very high affinity for haemoglobin, which is approximately 300 times greater than that of oxygen (\(O_{2}\)). When \(CO\) is inhaled, it binds to the iron atom in the haemoglobin molecule to form carboxyhaemoglobin, which is much more stable than…
