What affect does the presence of metal ions like Mg++ in the cell have on free energy of hydrolysis of ATP??

Definitely, Mg++ will have an affect on the free energy of hydrolysis of ATP, even as pH has an effect. How come?
The effect of Mg++ ions on ATP hydrolysis is actually quite complex. If you decrease the Mg++ concentration from about 100 mM to 1 mM, we see a decrease in the free energy of hydrolysis by about 1 kcal/mol. However, here's the interesting part. If you decrease the Mg++ even further, say, ...
