What Are Examples Of Exergonic And Endergonic Reactions?

What Are Examples Of Exergonic And Endergonic Reactions? Often, one chemical reaction feeds the next and endergonic reactions are coupled to exergonic reactions to give them enough energy to proceed. For example, firefly bioluminescence results from endergonic luminescence by luciferin, coupled with exergonic ATP release. Is this an endergonic or exergonic reaction?
