Unknown General 1d3ac9e6 About O2 dissociation curve, true is: A Affinity of O2 with Hb decreases as Hb attaches to O2 in linear fashion B 1 Hb attaches to 2 molecules of 2,3 DPG C O2 affinity will be equal in both HbF and HbA in the absence of 2, 3DPG is removed D Carboxy Hb increases releases of O2 in blood (shift O2 dissociation curve to right) High-Yield Explanation (Refer: Textbook of Medical Biochemistry By S Ramakrishnan. Pg no: 102) Affinity of Hb F for oxygen and carbon dioxide
