For the following reaction, hbo2 + co hbco + o2, which of the following will cause the release of carbon monoxide (co) from the carboxyhemoglobin (hbco)?

a. increasing the amount of oxygen.
b. increasing the amount of carbon monoxide.
c. no right choice.

The correct answer is a increase the amount of oxygen.

Explanation:

Hemoglobin contain 4 oxygen binding site,one oxygen binding site is present in each chain.The binding of oxygen to hemoglobin stabilizes the R state or relaxed state of hemoglobin.

    Carbon monoxide has many times more binding affinity to the hemoglobin.The binding of carbon monoxide to hemoglobin result in the formation of carboxyhemoglobin.

         From the above reaction it can be stated that if the amount of oxygen is increased inside our body then the increased amount of oxygen will displace the carbon monoxide molecules from the hemoglobin .
