WebThe multiple subunit structure of hemoglobin gives it important oxygen binding properties that are different than myoglobin's, consistent with hemoglobin's role in oxygen transport. In all vertebrates the oxygen transport protein is hemoglobin, a protein that can pick up oxygen in lungs or gills and deliver it to tissues. WebThe proportion of hemoglobin saturated with oxygen is not directly proportional to the oxygen pressure. As the oxygen pressure declines, hemoglobin gives up its oxygen with disproportionate rapidity, so that the major fraction of the oxygen can be released with a relatively small drop in oxygen tension.

WebAs pH rises, hemoglobin loses hydrogen ions from specific amino acids at key sites in its structure, and this causes a subtle change in its structure that enhances its ability to bind oxygen. When... WebIt is a positive relationship: at pressure increases, hemoglobin has a higher affinity or oxygen so more oxyhemoglobin is present. And when partial pressure of oxygen decreases, then hemoglobin has a lower affinity for oxygen and gives up more of it.
