WebThe protein inside (a) red blood cells that carries oxygen to cells and carbon dioxide to the lungs is (b) hemoglobin. Hemoglobin is made up of four symmetrical subunits and four heme groups. Iron associated with the heme binds oxygen. It is the iron in hemoglobin that gives blood its red color. WebHb is a red blood cell protein that plays an essential role in sustaining aerobic metabolism by transporting O 2 from the respiratory exchange surfaces (e.g., lungs, gills, or skin), where the partial pressure of O 2 (PO 2) is high, to the cells of respiring tissues, where the PO 2 is low and the partial pressure of CO 2 (PCO 2) is elevated by metabolic activity.
