Erythrocytes Survive 120 Days Hemoglobin * Globin: 4 folded polypeptide chains * Heme: Iron group in each polypeptide that binds 02 Enzymes: * Glycolytic: generate energy through glycolysis due to lack of mitochondria * Carbonic anhydrase: for transport of CO2 into HCO3 Erythropoiesis: * regeneration of new cells in the bone marrow Erythropoietin (hormone): * when kidneys detect not enough 02 they secrete this hormone which stimulates erythropoiesis‚ increasing 02 capacity
