Detailed explanation-1: -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.
Detailed explanation-2: -Oxygen is one of the substances transported with the assistance of red blood cells. The red blood cells contain a pigment called haemoglobin, each molecule of which binds four oxygen molecules. Oxyhaemoglobin forms. The oxygen molecules are carried to individual cells in the body tissue where they are released.
Detailed explanation-3: -Hemoglobin is a protein found in red blood cells. It contains iron, which allows it to transport oxygen. Each hemoglobin molecule can bind up to four oxygen molecules. This way, it can transport the oxygen from the lungs to the tissues that need it.
