Which one of the following gases converts haemoglobin into carboxy haemoglobin?
- A \(\mathrm{CO}\)
- B \(\mathrm{O}_2\)
- C NO
- D \(\mathrm{CO}_2\)
Answer & Solution
Correct Answer
(A) \(\mathrm{CO}\)
Step-by-step Solution
Detailed explanation
Carbon monoxide ( \(\mathrm{CO}\) ) converts haemoglobin
to carboxyhaemoglobin. When \(\mathrm{CO}\) is inhaled, it binds with haemoglobin in red blood cells with a much higher affinity compared to oxygen.
This binding forms carboxyhaemoglobin which prevents the normal binding of oxygen to. haemoglobin, leading to a decreased oxygen-carrying capacity of the blood.
