WebThe relationship between the partial pressure of O 2 (P O 2 ) and percentage saturation of the Hb with O 2 is graphically illustrated by a curve called oxygen dissociation curve. The haemoglobin is most saturated with oxygen in the pulmonary vein, as this vein is carrying oxygenated blood from the Iungs towards the left auricle of the heart. 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 … dick apley

What conformation is myoglobin? Mostly Alpha Helix, most nonpolar … dick argusLike hemoglobin, myoglobin is a cytoplasmic protein that binds oxygen on a heme group. It harbors only one globulin group, whereas hemoglobin has four. Although its heme group is identical to those in Hb, Mb has a higher affinity for oxygen than does hemoglobin. This difference is related to its different role: whereas hemoglobin transports oxygen, myoglobin's function is to store oxygen. dick anthony williams movies
