Cellular metabolism is the set of chemical reactions that occur within a cell to maintain life. These reactions involve the breakdown of nutrients to produce energy, the synthesis of biomolecules for cell structure and function, and the regulation of metabolic pathways. Cellular metabolism is essential for processes such as growth, repair, and reproduction, and disruptions in metabolism can lead to various diseases. Researchers study cellular metabolism to understand how cells obtain and utilize energy, how metabolic pathways are regulated, and how metabolism is linked to health and disease. This research area encompasses biochemistry, molecular biology, and systems biology, among other disciplines.
