<prompt> O2 dissociation curve is shifted to right in all except?HypercapneaRise in temperatureRaised 2, 3 DPG levelMetabolic alkalosis  <response>: Ans. is d i.e., Metabolic alkalosisHypercapnea raised CO2, rise in temprature and increased 2, 3 DPG cause righward shift of O2 dissociation curve.Metabolic alkalosis causes leftward shift.
