Which of These Factors Does Not Affect Hemoglobin's Affinity for Oxygen

Question

Which of these factors does not affect hemoglobin's affinity for oxygen?
A) RBC metabolic activity
B) temperature
C) electrolyte balance
D) the PO2 of blood
E) blood pH

Accepted Answer

Hemoglobin's affinity for oxygen is primarily affected by the PO2 of the blood, the blood pH, temperature, and RBC metabolic activity. Electrolyte balance does not directly affect hemoglobin's affinity for oxygen.
