Adenosine triphophste, ATP, is used to store energy within biological systems. It releases that energy by losing a terminal phosphate group, Pi, to form adenosine diphophate, ADP, through the hydrolysis reaction. The standard reaction Gibbs energy for hydrolysis of ATP to ADP is + 10 kJ mol at 298K. This assumes that the concentration of hydrogen ions is 1 mol/ L.
a) In biochemistry, it is common practice to assume an alternative, and more realistic, standard state for pH=7. What is the corresponding standard reaction Gibbs energy, denoted, for this biological standard state.
b) What is thr Gibbs energy of reaction in an environment at 37 C and pH =7 in which the ATP, ADP and Pi concentrations are all 1) 1.0 mmol/L, 2) 1 Micromol/L?
