When 1 molecule of glucose from glycogen stores is converted to lactate, the net energy gain is 3ATP.
What is anaerobic glycolysis?
- Anaerobic glycolysis is the pathway of conversion of glucose to lactate in the muscles in the absence of oxygen.
- In the skeletal muscles, glycogen breaks down to form glucose in the form of Glucose 1 phosphate (G1P).
- G1P gets converted to G6P.
- G6P enters glycolysis and produces ATP as energy source in the muscles.
- 2 ATP molecules are produced in this step.
- When there is enough oxygen, pyruvate releases energy through oxidative phosphorylation.
- In the absence of oxygen, pyruvate gets converted to lactate by lactic acid fermentation.
- This lactate then moves into the liver where it gets converted into pyruvate and then glucose.
- 6 ATP molecules are produced in this step.
