... the reactions necessary to keep cells and organisms alive must run against their thermodynamic potential, that is, in the direction of positive ⌬G. Among these are the synthesis of adenosine ... All naturally occurring processes proceed toward equilib- rium, that is, to a state of minimum potential energy. The third law of thermodynamics states that the entropy of any crystalline, perfectly o...
