Coupled reaction

WebATP-Coupled Reaction Process: Energy is either absorbed or released when a reaction occurs. This depends on the relative abilities to break bonds and forming bonds. Two important reactions occur in ATP coupling,namely, exergonic and endergonic reactions. Exergonic reaction: o Energy is emitted into the surroundings in an exergonic reaction. WebJun 16, 2024 · Energy coupling, by definition, stands for a concept of coupling two biological reactions; meaning energy generated from one reaction is used to drive the second reaction. Two different reactions or biological systems are coupled together or put into synchrony this way.
