Question
Read the following paragraph carefully.
Carbon monoxide combines with blood's haemoglobin to form a compound called ____ X
This compound does not allow haemoglobin to ____ Y oxygen, thus depriving our body cells of oxygen. This causes paralysis of respiratory organs and results in death due to suffocation. This makes CO gas a highly _____ Z one.
Identify the compounds X, Y and Z in the above paragraph:
Hint:
It is a highly toxic gas released due to incomplete combustion.
The correct answer is:
The correct option is b)
Carbon monoxide combines with hemoglobin to from carboxyhemoglobin. It reduces the oxygen absorbing ability of hemoglobin. This in turn deprives the body of oxygen which causes paralysis of respiratory organs or even death due to increased toxicity in blood. It is a highly poisonous gas.
