Calculate the value of AG am in a biological cell in which [ATP) 5.0 mM, CADP) 0.80 mM, and [HPO. 5.0 mM.

dG = dG° + RT*ln(Q)
T = 37°C = 310 K
R = 8.314 J/molK, dG° = -30500 J/mol
Q = [ADP][HPO4-2]/[ATP]
Q = (0.80*10^-3)(5*10^-3)/(5*10^-3) = 0.0008
dG = dG° + RT*ln(Q)
dG = -30500 + 8.314*310*ln(0.0008)
dG = -48878.75 J/mol
dG = -48.878 kJ/mol
this must be favouring product,s i.e. spontaneous, since dG < 0
answer is YES
