More generally, the terms exergonic and endergonic relate to the free energy change in any process, not just chemical reactions. An example of an exergonic reaction is cellular respiration. By contrast, the terms exothermic and endothermic relate to the overall exchange of heat during a process.
Exergonic reactions involve the formation of bonds; endergonic reactions involve the breaking of bonds. Exergonic reactions release energy; endergonic reactions absorb it. In exergonic reactions, the reactants have less chemical energy than the products; in endergonic reactions, the opposite is true. 54.
