WebThe changing oxygen affinity of Hb with oxygenation results in a sigmoid oxygen dissociation curve (Fig. 7.6) when the percentage saturation of Hb with oxygen is plotted against the partial pressure of oxygen (pO 2). The pO 2 at which Hb is 50% saturated is the P 50. The steepness of the middle portion of the curve is of great physiological ... WebAn oxygen–hemoglobin dissociation curve is a graph that describes the relationship of partial pressure to the binding of oxygen to heme and its subsequent dissociation from heme ( Figure 22.26 ). Remember that gases travel from an area of higher partial pressure to an area of lower partial pressure. http://hodsonhome.com/mna2001/chemphysics/o2curve.htm phonydiploma.com
