Metabolism refers to the chemical reactions that occur within a living organism to maintain life. These reactions are organized into metabolic pathways, where substances are transformed and energy is produced and consumed to perform various cellular processes. Metabolism is divided into two complementary categories: catabolism, where molecules are broken down to release energy, and anabolism, where energy is used to synthesize complex molecules from simpler ones. These metabolic processes allow organisms to grow, reproduce, maintain their structures, and respond to environmental changes. Enzymes play a crucial role in these reactions, acting as catalysts that allow the reactions to proceed rapidly and efficiently. The rate of metabolism, influenced by factors such as genetics, age, diet, and activity level, significantly impacts health and disease states in organisms, including humans. Understanding metabolism is essential in fields like medicine, fitness, and biology, as it is fundamental to all cellular functions and life itself.
