It is one of the two quaternary forms of hemoglobin that predominates in absence of oxygen. It has a lower affinity for substrates and, hence, lower catalytic activity. 6. R state:R stands for relaxed state. 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 a steep slope at low partial pressures of oxygen and a more gradual slope at higher partial pressures. This allows hemoglobin to bind oxygen …
