During the process of transport and delivery of from our lungs to muscle , there is equilibrium b/w species
CO and the protein haemoglobin
NO and the prortein haemoglobin
and the protein haemoglobin
none
Equilibrium involving O2 molecules and the protein haemoglobin plays a crucial role in the transport and delivery of O2 from our lungs to our muscles.
Similar equilibrium involving CO molecules and haemoglobin account for the toxicity of CO.
In the given process, the equilibrium is between O2 and the protein haemoglobin
Therefore, the option number(3) is correct.
