Answer 2

Red blood cells contain a molecule called hemoglobin, which binds and transports oxygen through our bodies. Hemoglobin is made up of four protein chains that each bind an additional ring-shaped chemical structure called heme. Our red blood cells are red because of the heme groups in hemoglobin.
