•糖酵解过程 GLYCOLYSIS Mostly endergonic reactions Mostly exergonic reactions 可分为二个阶段： Triose phosphate isomerase Aldolase Glyceraldehyde-Dihydroxyacetone 第一个阶段： 3phosphate phosphate Fructose (G3P) (DAP) Phosphofructo 1.6-bis Ghceraldehyde 2 NAD7 由葡萄糖生成2个三碳糖 kinase prosphate 3-prosphate (F1,66P) Phosphoglucose Fructose denydnogenase +2a0+⊙ isomerase 6-phosphate 2 1.3Bisphosphcglycerate(BPG) (F6P) ATP Glucose ADP Phosphoglycerate 2 ADP) Hexokinase 6-phosphate →2T0 Glucose GP) 2 3-Phosphoglycerate (3PG) ATP ADP Phosphoglycerate mutase The first 4 reactions split one si-carbon guccse 2 2-Phosphoglycerate (2PG) into 2 3-carbon molecules,using the energy from Enclase 2 ATPs. The next 5 reactions produce 2 molecules of 2 Phosphocnolpyruvate(PEP) pyruvate.reduce 2 NADto NADH,and produce 2 ADP 4 molecules of ATP. kinase 2 ATP The net gain for glycolysis is 2 ATPs. 2Pyruvate•糖酵解过程 可分为二个阶段： 第一个阶段： 由葡萄糖生成2个三碳糖
