Due to the Root effect, which is only observed in the ray-finned fish, decreasing the pH of a solution of hemoglobin will:. a. decrease the affinity of hemoglobin for oxygen and lower the maximum percent saturation of the hemoglobin increase the affinity of hemoglobin for oxygen and shift the oxygen equilibrium curve to the left.
b. increase the affinity of hemoglobin for oxygen and raise the maximum percent saturation of the hemoglobin decrease the affinity of hemoglobin for oxygen and shift the oxygen equilibrium curve to the left.
c. increase the affinity of hemoglobin for oxygen and lower the maximum percent saturation of the hemoglobin
