{{Main|Catabolism}}<br />
Catabolism is the set of metabolic processes that break down large molecules. These include breaking down and oxidizing food molecules. The purpose of the catabolic reactions is to provide the energy and components needed by anabolic reactions which build molecules. The exact nature of these catabolic reactions differ from organism to organism, and organisms can be classified based on their sources of energy, hydrogen, and carbon (their [[primary nutritional groups]]), as shown in the table below. Organic molecules are used as a source of hydrogen atoms or electrons by [[organotroph]]s, while [[lithotroph]]s use inorganic substrates. Whereas [[phototroph]]s convert sunlight to [[Potential energy#Chemical potential energy|chemical energy]], [[chemotroph]]s depend on [[redox]] reactions that involve the transfer of electrons from reduced donor molecules such as [[organic molecule]]s, [[hydrogen]], [[hydrogen sulfide]] or [[Ferrous|ferrous ions]] to [[oxygen]], [[nitrate]] or [[sulfate]]. In animals, these reactions involve complex [[organic molecule]]s that are broken down to simpler molecules, such as [[carbon dioxide]] and water. [[photosynthesis|Photosynthetic]] organisms, such as plants and [[cyanobacteria]], use similar electron-transfer reactions to store energy absorbed from sunlight.</div>FuzzyBot
