Major pathways in human erythrocytes. The Embden-Meyerhof pathway (glycolytic pathway) converts one molecule of glucose to two molecules of lactate
generating two net molecules of ATP. Rapoport-Luebering shunt is a unique pathway to generate 2,3-bisphosphoglycerate. Human erythrocyte hexose
monophosphate (HMP) shunt functions mainly for producing NADPH, which is essential for maintaining a high concentration of GSH. BPGM =
bisphosphoglycerate mutase; BPGP = bisphosphoglycerate phosphatase; GA-3-PD = glyceraldehyde-3-phosphate dehydrogenase; GPI =
glucosephosphate isomerase; GR = glutathione reductase; GSH-Px = glutathione peroxidase; G6PD = glucose-6-phosphate dehydrogenase; LDH =
lactate dehydrogenase; MPGM = monophosphoglycerate kinase; PFK = phosphofructokinase; PGK = phosphoglycerate kinase; PK = pyruvate kinase;

6PGD = 6-phosphogluconate dehydrogenase; TPI = triosephosphate isomerase.
