Metabolism meaning

Metabolism encompasses all the chemical processes that occur within a living organism to maintain life. These processes include catabolism, where food and nutrients are broken down to produce energy, and anabolism, where energy is used to build and repair tissues and synthesize necessary molecules. Metabolic rate, the speed at which these processes occur, varies between individuals and is influenced by factors such as age, sex, muscle mass, and overall health. Proper metabolic function is essential for growth, reproduction, and maintaining cellular and systemic homeostasis. Metabolic disorders, such as diabetes and thyroid diseases, can disrupt these processes and require medical management.
