Ion pump energetics
Textbooks quote the value of standard free energy change for the hydrolysis of ATP equal to -7.3 kcal/mole. A certain molecular machine uses one ATP per ste and does useful work equal to 14 kT. Reconcile these statements, using the fact that typical intracellular concentration are [ATP] = 0.01, [ADP] = .001, and [Pi}= .01.
