Ion pump energetics is the focal topic.

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.  This job reconciles these statements, using the fact that typical intracellular concentration are [ATP] = 0.01, [ADP] = .001, and [Pi}= .01.


Solution Summary

This job reacts to standard free energy change for the hydrolysis of ATP.
