Energy Coupling

Definition

Energy coupling refers to the process in which the energy released from one reaction is used to drive another reaction, allowing for efficient energy transfer and utilization within a system. This concept is crucial in various applications, especially in technologies that require precise energy management, such as driver technologies. By linking exergonic (energy-releasing) reactions with endergonic (energy-consuming) processes, energy coupling enables systems to perform work efficiently and sustainably.
