WebOxyhaemoglobin dissociation curves are S-shaped. They show the relationship between the partial pressure of oxygen and the saturation of haemoglobin with oxygen. Saturation can have an effect on affinity. A-level Biology – Transport of Oxygen Gradient of the curve is initially shallow. WebThe mechanisms behind the oxygen–hemoglobin saturation/dissociation curve also serve as automatic control mechanisms that regulate how much oxygen is delivered to different tissues throughout the body. This is important because some tissues have a higher metabolic rate than others.
