What type of reaction is cellular respiration classified as?

Cellular respiration is classified as an exergonic reaction because it involves the breakdown of glucose and other molecules to release energy. In an exergonic reaction, the free energy of the products is lower than that of the reactants, resulting in a net release of energy, which is captured in the form of ATP (adenosine triphosphate) used by the cell for various functions.

During cellular respiration, glucose is oxidized, and its chemical energy is transformed into usable energy for the cell. This process includes glycolysis, the citric acid cycle, and oxidative phosphorylation, all of which lead to the production of ATP. Since energy is released during these steps, the overall process of cellular respiration is labeled as exergonic. The significant energy release is crucial for supporting life processes, allowing organisms to carry out essential functions.
