WebThe correct answer is 'curve b'. Curve A represents myoglobin, with a higher affinity for oxygen than hemoglobin and a sideways U-shaped (hyperbolic) curve. Fetal … WebThe reverse process occurs in the tissues, as more oxygen molecules depart the hemoglobin, , the hemoglobin's affinity is reduced. There are two models for how affinity change occurs in molecules such as hemoglobin. The concerted model suggests that all the cooperative binding sites change at the same time. fmc cookers
