Metabolism is the overall process through which living systems acquire and utilize the [[free energy]] they need to carry out their various functions.  They do so by coupling the [[exergonic]] reactions, or spontaneous reactions but this does not imply that the reaction will take place unconstrained, of nutrient oxidation to the endergonic processes, or nonspontaneous processes that require the use of [[free energy]], required to maintain the living state such as the performance of mechanical work, the active transport of molecules against concentration gradients, and the biosynthesis of complex molecules.
