2. CONTENT INTRODUCTION GLYCOLYTIC PATHWAY AND SUBSTRATE LEVEL PHOSPHORYLATION CONCLUSION

3. INTRODUCTION Glycolysis ( Glycos = glucose and lysis = breakdown) is a process where one glucose molecule converted into 2 molecule of pyruvate . This process takes place in the cytosol . Hence it is also called cellular respiration. It is also known as Embden -Meyerhof- Parnas (EMP) pathway. There are two phases in glycolysis - Preparatory phase Payoff phase

5. Reaction No. Consuption / gain of ATP Gain of NADH 1 Consumption 1 ATP 3 Consumption 1 ATP 6 Gain 2 NADH 7 Gain 2 ATP 10 Gain 2 ATP Net gain of ATP = 4-2=2 and NADH=2 NET ENERGY YEILD IN GLYCOLYSIS:-

6. Substrate level phosphorylation in glycolysis Step-7 1,3-bisphosphoglycerate 3-Phosphoglycerate ADP ATP Step- 10 Phosphoenolpyruvate Pyruvate ADP ATP Phosphoglycerate kinase Pyruvate kinase

7. CONCLUSION Substrate level phosphorylation in glycolysis is a vital process that contribute to ATP production,crucial for cellular energy metabolism,particularly in anaerobic condition. **************************
