WebSep 2, 2024 · It is a major pathway for ATP synthesis in tissues lacking mitochondria, g. erythrocytes, cornea, lens etc. Glycolysis occurs in the absence of oxygen (anaerobic) or in the presence of oxygen (aerobic). Lactate is the end product under anaerobic condition. In the aerobic condition, pyruvate is formed, which is then oxidized to CO 2 and H 2 O. WebEnolases are metalloenzymes typically localized in the cytosol that participate in glycolysis by converting 2-phospho-d -glycerate to phosphoenolpyruvate. Despite their defined metabolic role, enolases are also surface-localized and can mediate plasminogen binding ( Pancholi, 2001 ). claudia lummis houston
