In a patient with chronic anemia, which adaptation causes increased oxygen delivery to tissues due to the altered hemoglobin binding affinity?

💡 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.
