<prompt> About O2 dissociation curve, true is:Affinity of O2 with Hb decreases as Hb attaches to O2 in linear fashion1 Hb attaches to 2 molecules of 2,3 DPGO2 affinity will be equal in both HbF and HbA in the absence of 2, 3DPG is removedCarboxy Hb increases releases of O2 in blood shift O2 dissociation curve to right  <response>: Refer: Textbook of Medical Biochemistry By S Ramakrishnan.
