Biological changes at the molecular level are governed by chemical thermodynamics. Coupling a reaction with the hydrolysis of ATP, for example, changing the equilibrium constant of the process by a factor of approximately 108. Coupling a thermodynamically unfavored process with one that is thermodynamically favored is a commonly encountered biochemical strategy.
