Basic function of hemoglobin is
High-Yield Explanation
The red, oxygen-carrying pigment in the red blood cells of veebrates is hemoglobinEach of the four iron atoms in hemoglobin can reversibly bind one O2 moleculeIt takes up O2 from lungs due to increase in pO2 and released in tissues where pO2 is lessIn this way, 250 mL of O2 per minute is transpoed from the blood to the tissues at rest.Ref: Ganong's Review of Medical Physiology Twenty-Third Edition Page No: 610
