Detailed explanation-1: -About 70 percent of your body’s iron is found in the red blood cells of your blood called hemoglobin and in muscle cells called myoglobin . Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues. Myoglobin, in muscle cells, accepts, stores, transports and releases oxygen.
Detailed explanation-2: -This iron molecule is responsible for binding to oxygen to transport it around the body (carrying up to four oxygen molecules). Oxygen binds to haemoblobin because it is not very soluble in blood, therefore, to meet the body’s demands for oxygen, haemoglobin must carry oxygen. Haemoglobin is thus a carrier molecule.
Detailed explanation-3: -What Is the Function of Red Blood Cells? Red blood cells carry oxygen from our lungs to the rest of our bodies.
