Which of the following will decrease the affinity of oxygen for hemoglobin at low oxygen partial pressures and shift the oxyhemoglobin saturation curve to the right, resulting in increased oxygen unloading for active tissues?
Select one:
a. high CO2
b. low H+
c. low temperature
d. high hemoglobin levels
e. low CO2
A. High CO2 is the correct answer.
High CO2 will shift the curve to the right and cause O2 unloading at the level of tissue.
An eg. is given below
Unsat. & Sat. means unsaturated and saturated.
Red. Means reduced.
Hb is hemoglobin
P 50= partial pressure.
