Detailed explanation-1: -Answer: c. it transports oxygen to human body tissues.
Detailed explanation-2: -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-3: -Hemoglobin (Hb) constitutes a vital link between ambient O2 availability and aerobic metabolism by transporting oxygen (O2) from the respiratory surfaces of the lungs or gills to the O2-consuming tissues.
Detailed explanation-4: -What Is the Function of Red Blood Cells? Red blood cells carry oxygen from our lungs to the rest of our bodies.
Detailed explanation-5: -Hemoglobin (Heme + Globin) The protein hemoglobin is a molecule which is responsible for carrying almost all of the oxygen in the blood. It is composed of four subunits, each with a heme group plus a globin chain. The heme group is composed of a porphyrin ring which contains an iron (Fe) atom in its center.
