Question 12 of 30 Incorrect Map General Chemistry 4th Edition McQuarrie Rock Gallo University Science Books presented by Sapling Learning 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 for which AG rxn which [ATP] = 5.0 mM, [ADP] = 0.70 mM , and [HPO421-5.0 mM n -30.5 kJ/mol at 37.0 °C and pH 7.0. Calculate the value of AGrxn in a biological cell in Number Incorrect Be sure to convert the concentrations from millimolar to molar. 31.42 kJ/ mol rxn Is the hydrolysis of ATP spontaneous under these conditions? O yes no Previous # Try Again Next Exit

Explanation / Answer

dG = dG° + RT*ln(Q)

Q = [ADP][HPO4-2] /([ATP]

Q = (0.7*10^-3)(5*10^-3)/(5*10^-3) =  0.0007

dG = (-30500) + (8.314*37+273) * ln(0.0007)

dG = -34717.85

dG = -34.72 kJ/mol

since dG < 0, this must be spontaneous
