Anyagcsere, often referred to as metabolism, encompasses all the chemical processes that occur within a living organism in order to maintain life. These processes allow organisms to grow, reproduce, maintain their structures, and respond to their environments. Metabolism is broadly divided into two categories: catabolism and anabolism.

Catabolism involves the breakdown of complex molecules into simpler ones, releasing energy in the process. This released energy is then captured and used to power other cellular activities. Examples of catabolic processes include the digestion of food and cellular respiration.

Anabolism, conversely, is the synthesis of complex molecules from simpler ones, requiring energy input. These complex molecules are used for growth, repair, and the synthesis of essential cellular components. Examples of anabolic processes include protein synthesis and the formation of new tissues.

The balance between catabolism and anabolism is crucial for maintaining homeostasis, the stable internal environment of an organism. Hormones, such as insulin and thyroid hormones, play significant roles in regulating metabolic rates. Factors like diet, physical activity, age, and genetics can influence an individual's metabolic rate. A faster metabolic rate means the body burns more calories at rest. Conversely, a slower metabolic rate results in fewer calories being burned. Disruptions in metabolic processes can lead to various health conditions, including obesity, diabetes, and thyroid disorders. Understanding metabolism is fundamental to comprehending biological functions and developing strategies for health and disease management.
