Anyagcsere, often translated as metabolism, refers to the sum of all chemical processes that occur within a living organism in order to maintain life. These processes are essential for growth, reproduction, and maintaining the structure of cells and tissues. Metabolism can be broadly divided into two main categories: anabolism and catabolism.

Anabolism is the constructive part of metabolism, where smaller molecules are used to build larger, more complex ones. This process requires energy, which is often supplied by the breakdown of food molecules. Examples of anabolic processes include the synthesis of proteins from amino acids or the formation of glycogen from glucose. These reactions lead to growth and repair within the body.

Catabolism, on the other hand, is the destructive part of metabolism, where larger molecules are broken down into smaller ones. This process releases energy, which can then be used by the organism for various functions, including muscle contraction, nerve impulse transmission, and the maintenance of body temperature. Examples of catabolic processes include the digestion of carbohydrates into glucose or the breakdown of fats into fatty acids and glycerol.

The balance between anabolism and catabolism is crucial for maintaining homeostasis, the stable internal environment of the body. Hormones, such as insulin and glucagon, play a significant role in regulating metabolic processes, ensuring that the body has the necessary energy and building blocks to function correctly. Disruptions in metabolism can lead to various health conditions, including obesity, diabetes, and metabolic syndrome.
