Exergonic Reaction (Lat. Ex - From, Gr. Ergon - Work)

An exergonic reaction (from Latin ex - “from” and Greek ergon - “work”) is a chemical reaction that occurs with the release of energy in the form of heat, light or other forms of energy. In such reactions, the energy associated with chemical bonds in the reactants is released when new bonds are formed in the reaction products.

An example of an exergonic reaction is the burning of wood. During combustion, wood reacts with oxygen from the air to form carbon dioxide and water, releasing large amounts of heat and light. This energy can be used to heat a room or drive machinery.

Another example of an exergonic reaction is the hydrolysis of ATP (adenosine triphosphate), which is the main source of energy for cellular processes in organisms. Hydrolysis of ATP results in the formation of ADP (adenosine diphosphate) and a phosphoric acid residue, releasing energy that is used for the synthesis of proteins and other important molecules.

Exergonic reactions are the opposite of endergonic reactions, which require energy to occur. It is important to note that most biological reactions are endergonic, but they can be carried out due to the presence of energy released as a result of exergonic reactions.

In conclusion, exergonic reactions play an important role in various processes, including combustion, cell metabolism, and industrial production. Understanding the mechanisms of exergonic reactions is of great importance for the development of new technologies and improvement of existing production methods.
