Evaluate the physiological significance of hemoglobin transitioning from the T state in tissues to the R state in lungs.

• A. The transition prevents hemoglobin from releasing CO2 and H+ in the lungs and binding oxygen.
• B. The transition has no effect on hemoglobin's ability to release CO2 and H+ or bind oxygen.
• C. The transition allows hemoglobin to release CO2 and H+ in the lungs and bind oxygen efficiently.
• D. The transition causes hemoglobin to bind CO2 and H+ in the lungs instead of oxygen.

Answer: (C)
