COUPLED REACTION Meaning and
Definition
-
A coupled reaction refers to a chemical or biological reaction in which the energy released from one reaction is utilized to drive another reaction, thereby allowing both reactions to proceed. It involves the transfer of energy or reactants between the two reactions, creating a dependency between them.
In a coupled reaction, the energy released by an exergonic (energy-releasing) reaction is harnessed to fuel an endergonic (energy-absorbing) reaction. This energy transfer is mediated through a compound called an energy carrier, such as ATP (adenosine triphosphate) in biological systems. ATP acts as a universal energy currency, storing and releasing energy as required by the cellular processes.
The two reactions in a coupled reaction are typically interconnected and interdependent. The energy released by the exergonic reaction is used to power the endergonic reaction, which may involve the synthesis of molecules or the transport of ions across a membrane.
Coupled reactions are crucial for the maintenance and functioning of living organisms. They enable the efficient utilization of energy and resources, as well as the control of reactions that are energetically unfavorable on their own. By coupling reactions together, a series of interconnected reactions can be orchestrated to drive complex processes like metabolism, muscle contraction, or nerve impulse transmission.
In summary, a coupled reaction describes a connection between two reactions in which the energy released by one reaction is utilized to drive the other reaction, allowing them to occur simultaneously and interdependently.

Etymology of COUPLED REACTION
The word "coupled" comes from the Old French word "copler", which means "to join, fasten together". It ultimately derives from the Latin word "copulare", meaning "to connect, join, bind". The use of "coupled" in the context of chemical reactions refers to the coupling or linking of two or more reactions together.
The term "coupled reaction" is commonly used in biochemistry and refers to a pair of reactions that are connected, where the product of one reaction serves as a reactant for the other. This coupling mechanism allows the overall reaction to occur efficiently, as the energy and/or molecules produced in one reaction are immediately utilized in the other. The etymology of "coupled reaction" specifically ties back to the general meaning of "coupled" as joining or connecting two or more entities in a coordinated way.
