I am currently studying the metabolic pathways for biochemistry and I am not quite clear in which reactions of glycolysis magnesium is involved.
So I have now found out that magnesium is present in the three ATP-dependent reactions (1st, 3rd and 10th reactions), but also in the 2nd, 7th, 8th and 9th steps.
According to this diagram:
In our university we have been tought, that Magnesium is present in all ATP reactions, but also in Step 2... this is what causes confusion for me:
