WebOct 29, 2015 · Oxyhemoglobin dissociation curve. This graph shows how changes in the partial pressure of oxygen (PO2) influence oxygen (O 2) binding to, and dissociation from, hemoglobin (Hb). P O 2 is plotted on the x-axis from 0 to 100 mm Hg (millimeters of mercury). The upper range of 100 mm Hg is chosen because it represents the value of P … WebHemoglobin (Hb) is a complex protein molecule. It consists of four separate polypeptide chains called protein subunits. It is made up of two identical alpha-chains and two identical beta-chains. Each chain forms a 3-dimensional molecule with iron (Fe) intertwined in the center. Each Fe group is capable of combining loosely with one molecule of O 2.

WebThe oxygen dissociation curve is a graph with oxygen partial pressure along the horizontal axis and oxygen saturation on the vertical axis, which shows an S-shaped relationship.
