WebIron associated with the heme binds oxygen. It is the iron in hemoglobin that gives blood its red color. It is easier to bind a second and third oxygen molecule to Hb than the first molecule. This is because the hemoglobin … WebJun 8, 2024 · The red coloring of blood comes from the iron-containing protein hemoglobin (see [a] in ) The principal job of this protein is to carry oxygen, but it transports carbon dioxide as well. Hemoglobin is packed into red blood cells at a rate of about 250 million molecules of hemoglobin per cell.
