What happens when carbon monoxide binds to hemoglobin?

WebYeah got the right idea, but this doesn't mean that CO2 doesn't decrease O2's affinity for hemoglobin. Like you said, CO2 can bind to the hemoglobin subunit causing a conformational change of the protein decreasing O2 affinity for the molecule; this is known as allosteric inhibition.ALSO CO2 can react with H2O eventually leading to the creation … WebHemoglobin contains four heme groups each capable of reversibly binding to one oxygen molecule. Oxygen binding to any of these sites causes a conformational change in the protein, facilitating binding to each of the other sites.
