Mature erythrocytes are bound by a plasma membrane, but lack a nucleus (are anucleate) and have essentially no organelles. In fact, they are little more than “bags” of hemoglobin (Hb), the … WebDec 15, 2005 · Because of the lack of nuclei and mitochondria, mature red blood cells are incapable of generating energy via the (oxidative) Krebs cycle. Instead, erythrocytes depend on the anaerobic conversion of glucose by the Embden-Meyerhof pathway for the generation and storage of high-energy phosphates ( Figure 1 ). canal crossing new orleans
