The gas that binds strongly with hemoglobin is:
Correct answer: A. Carbon monoxide
- A. Carbon monoxide
- B. Carbon dioxide
- C. Methane
- D. Nitrogen oxide
Explanation
Carbon monoxide binds to hemoglobin much more strongly than oxygen. Its presence keeps oxygen from binding to hemoglobin. Carbon monoxide is highly poisonous gas and causes suffocation if inhaled. It binds blood haemoglobin more strongly than oxygen thus excluding oxygen from normal respiration.
