In which reactions of glycolysis is magnesium involved?
In the 1st step where glucose is converted to glucose-6- phosphate by the enzyme hexokinase, in the 3rd step where fructose-6-phosphate is converted to fructose-1,6-bisphosphate by the enzyme fructose-1,6-bisphosphatase and in the last reaction where 2 phosphoenolpyruvate is converted to pyruvate by the enzyme pyruvate kinase.. In this 3 reaction Magnesium is needed as they are ATP dependent reaction and Magnesium stabilises the ATP in this reaction and help the reactions to proceed faster.
