What is the net energy gain when 1 molecule of glucose from glycogen stores is converted to lactate?

Sagot :

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.
