A critical reaction in the production of energy to do work or drive chemical reactions in biological systems is the hydrolysis of adenosine triphosphate, ATP, to adenosine diphosphate, ADP, as described by
ATP(aq) + H20(l) -----> ADP (aq) + HPO42-(aq)
for which ÎG°rxn = â30.5 kJ/mol at 37.0 °C and pH 7.0. Calculate the value of ÎGrxn in a biological cell in which [ATP] = 5.0 mM, [ADP] = 0.40 mM, and [HPO42â] = 5.0 mM.
Delta Grxn= ?
Is the hydrolysis of ATP spontaneous under these conditions? Yes/No
