WebThe oxygen-hemoglobin dissociation curve is a graphical representation of the relationship between the amount of oxygen bound to hemoglobin and the partial pressure of oxygen in the blood. The curve is sigmoidal, with … WebWhen the oxygen saturation percentage is plotted against the oxygen partial pressure, or pO2, an S-shaped or sigmoid curve is obtained. It is called the oxygen dissociation curve. Due to the cooperative binding of oxygen to haemoglobin, the binding of oxygen initially rises with an increase in pO2. Haemoglobin's affinity for oxygen is raised by ... WebJul 30, 2024 · The pH of the blood is another factor that influences the oxygen–hemoglobin saturation/dissociation curve (see Figure 2). The Bohr effect is a phenomenon that arises from the relationship between pH and oxygen’s affinity for hemoglobin: A lower, more acidic pH promotes oxygen dissociation from hemoglobin. In contrast, a higher, or more ... scotlund haisley
