Question
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(1)
→ ADP(aq) + HPO (aq)
for which AGxn
= –30.5 kJ/mol at 37.0 °C and pH 7.0. Calculate the value of AGrn in a biological cell in which
[ATP] = 5.0 mM, [ADP] = 0.30 mM, and [HPO,] = 5.0 mM.
AGxn =
kJ/mol
TOOLS
x10
Is the hydrolysis of ATP spontaneous under these conditions?
yes
no
