- P3D.2 In biological cells, the energy released by the oxidation of foods is stored in adenosine triphosphate (ATP or ATP“).The essence of ATP's action is its ability to lose its terminal phosphate group by hydrolysis and to form adenosine diphosphate (ADP or ADP): ATP* (aq) + H,O() → ADP* (aq) + HPO (aq) + H,O*(aq) At pH = 7.0 and 37°C (310K, blood temperature) the enthalpy and Gibbs energy of hydrolysis are A,H =-20kJ mol and A,G=-31 kJ mol", respectively. Under these conditions, the hydrolysis of 1 mol ATP“(aq) results in the extraction of up to 31kJ of energy that can be used to do non- expansion work, such as the synthesis of proteins from amino acids, muscular contraction, and the activation of neuronal circuits in our brains. (a) Calculate and account for the sign of the entropy of hydrolysis of ATP at pH = 7.0 and 310K.
