← Human Body & HealthDuring hemorrhagic shock, the kidneys increase 2,3-BPG production in red blood cells; which consequence follows in systemic oxygen transport?
A)Increased hemoglobin oxygen affinity
B)Decreased red blood cell glycolysis
C)Enhanced oxygen release to tissues✓
D)Reduced carbon dioxide carrying capacity
💡 Explanation
Increased 2,3-BPG levels reduce hemoglobin's oxygen affinity via allosteric modulation, facilitating oxygen unloading in peripheral tissues. Because of the Bohr effect, this adaptation ensures oxygen delivery to hypoxic tissues; therefore, enhanced oxygen release occurs, rather than increased oxygen affinity or reduced CO2 carrying capacity.
