Explanation:
Detailed explanation-1: -Hemoglobin is the oxygen-carrying protein that is found within all RBCs. It picks up oxygen where it is abundant (the lungs) and drops off oxygen where it is needed around the body. Hemoglobin is also the pigment that gives RBCs their red color.
Detailed explanation-2: -Hemoglobin contains iron, which allows it to pick up oxygen from the air we breathe and deliver it everywhere in the body. You can think of hemoglobin as the iron ("heme"), oxygen transport protein, ("globin") found in red blood cells.
Detailed explanation-3: -Hemoglobin is an allosteric protein. When one heme group in hemoglobin binds oxygen, it is easier for successive oxygen molecules to bind at the remaining three sites.
