Haemoblobin is a Fe containing protein responsible for oxygen transport in the blood. The curves given below idicate the percentage suturation of haemoglobin by O_(2) as a funcion of partial pressure of O_(2). Which of the following statement/s is/are correct for the given curves? I. In presence of CO_(2), higher P_(O_(2)) is needed for a given percentage saturation. II. In presence of CO_(2), lower P_(O_(2)) is needed for a give percentage saturation. III. The maximum percentgae saturation is not affected by the presence of CO_(2) IV. In the absence of CO_(2), maximum saturation of haemoglobin occurs at lower p_(O_(2)).
