ATP + H2O <---> ADP + Pi
Calculate the ΔG for ATP hydrolysis when the concentrations of ATP, ADP, and Pi are all 1M
R = 1.98 x 10-3
T = 310 kelvin
ΔGº = -30.5 kJ/mol
Homework Answers
Q of reaction = [ADP] [Pi] / [ATP]
= ( 1M) ( 1M) / ( 1M)
= 1
dG of reaction = dGo + RT ln (Q)
= - 30.5 KJ/mol + ( RT) ln ( 1) ( ln 1 = 0 )
= - 30.5 KJ/mol
Thus dG for ATP hydrolyisis is - 30.5 KJ/mol

Calculate the actual free energy of synthesis of ATP in human erythrocytes. The standard free energy of hydrolysis of ATP is -30.5 kJ/mol, and the concentrations of ATP, ADP, and Pi in an erythrocyte (all in M) are as follows: [ATP] = 2.25 X 10 –3; [ADP] = 0.25 X 10-3; and [Pi] = 1.65 X 10–3. Assume that the temperature is 37 oC and the pH is 7.0.
The value of the standard free energy (∆G°’) for the hydrolysis of ATP (ATP + H2O -> ADP + Pi)...
The value of the standard free energy (∆G°’) for the hydrolysis of ATP (ATP + H2O -> ADP + Pi) is relatively difficult to determine because of the small concentration of ATP remaining at equilibrium. The value can be determined from the equilibrium constant of two related chemical reactions. Glucose-6-phosphate + H2O -> glucose + Pi ; k’eq = 270 ATP + glucose -> ADP + glucose-6-phosphate ; K’eq = 890 From this information, calculate the standard free energy of...
