Bacterial Metabolism
Bacterial Metabolism: Introduction: Metabolism refers to all the biochemical reactions that occur in a cell or organism. The study of bacterial metabolism focuses on the chemical diversity of substrate oxidations and dissimilation reactions ,which normally function in bacteria to generate energy. metabolism has an energy-generating component, called catabolism (exergonic), and an energyconsuming, biosynthetic component, called anabolism (andergonic). Catabolic reactions or sequences produce energy as ATP, which can be utilized in anabolic reactions to build cell material from nutrients in the environment. Metabolic pathways of energy generation (ATP) Carbohydrates (particularly glucose), lipids, and protein are the most commonly oxidized compounds. Biologic oxidation of these organic compounds by bacteria results in synthesis of ATP as the chemical energy source. This process also permits generation of simpler organic compounds (precursor molecules) needed by the bacteria ce...
