← Human Body & HealthIn a patient with chronic anemia, which adaptation causes increased oxygen delivery to tissues due to the altered hemoglobin binding affinity?
A)Increased erythropoietin production independently
B)Reduced erythrocyte membrane permeability overall
C)Decreased activity of carbonic anhydrase
D)Elevated red blood cell 2,3-BPG levels✓
💡 Explanation
Elevated 2,3-BPG levels within red blood cells reduce hemoglobin's oxygen affinity, because this allosteric modulator stabilizes the T-state, promoting oxygen release in tissues. Therefore, increased 2,3-BPG enhances oxygen delivery, rather than reducing erythropoietin effects or altering membrane permeability.
