![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 the reaction
ATP(aq) + H,O(I)
ADP(aq) + HPO-(aq)
for which AGrxn
= -30.5 kJ/mol at 37.0 °C and pH 7.0. Calculate the value of AGrxn in a biological cell in which
[ATP] = 5.0 mM, [ADP] = 0.40 mM, and [HPO-] = 5.0 mM.
