WebHemoglobin is a protein in red blood cells that moves oxygen and carbon dioxide between the lungs and body tissues. This article discusses the test used to detect and measure the amount of hemoglobin derivatives in your blood. How the Test is Performed The test is done using a small needle to collect a sample of blood from a vein or an artery. 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.
