Anyagcseréjével refers to the metabolic processes occurring within a living organism. Metabolism is a complex series of chemical reactions that sustain life, enabling organisms to grow, reproduce, maintain their structures, and respond to their environments. These processes are broadly divided into two main categories: catabolism and anabolism.

Catabolism involves the breakdown of complex molecules into simpler ones, releasing energy in the process. For example, the digestion of food breaks down carbohydrates, fats, and proteins into smaller components that the body can absorb and utilize. This energy is then captured in the form of adenosine triphosphate (ATP), the primary energy currency of cells.

Anabolism, on the other hand, is the constructive part of metabolism. It involves the synthesis of complex molecules from simpler ones, requiring energy. This process is essential for building and repairing tissues, synthesizing hormones, enzymes, and other vital molecules. For instance, protein synthesis from amino acids is an anabolic process.

The rate at which these metabolic processes occur is known as metabolic rate. This rate is influenced by various factors, including age, sex, genetics, muscle mass, and physical activity level. A higher metabolic rate means the body burns more calories at rest. Maintaining a balanced metabolism is crucial for overall health and well-being, as disruptions can lead to various health issues.
