WebLike 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 of HCO3- and H+, the H+ protons will reduce the pH of the environment which lowers Hb's affinity for O2. Webrelationship between pO2 and binding is initially shallow but due to co-operativity binding facilitates further binding so curve steepens rapidly as pO2 rises until saturation. overall …
