Increase in P50 in oxygenation curve is due to decrease in: (A) PH, (B) Oxygen, (C) Temperature, (D) CO2
Answer is A. The strength with which oxygen binds to hemoglobin is affected by several factors. These factors shift or reshape the oxyhemoglobin dissociation curve. A rightward shift indicates that the hemoglobin under study has a decreased affinity for oxygen. ... Left shift: higher O2 affinity Ref: guyton and hall textbook of medical physiology 12 edition page number: 354,355,356
