Which statements are correct for oxyhaemoglobin dissociation curve ? (A) This curve is sigmoid (B) When CO_(2) concentration increases, then this curve shifts towards right side (C) Low temperature is favourable for dissociation of oxygen grom oxyhaemoglobin (D) Binding of oxygen with haemoglobin is primarily related to partial pressure of O_(2)

The circulation of blood in human body supplies O_(2) and releases CO_(2) . The concentration of O_(2) and CO_(2) is variable but on the average, 100 mL blood contains 0.02 g of O_(2) and 0.08 g of CO_(2) . Calculate the volume of O_(2) and CO_(2) at 1 atmosphere and body temperature of 37^(@)C assuming 10 L of blood in human body.
