Metabolism encompasses all the biochemical reactions that occur within an organism to sustain life. It can be divided into two main categories:
* Anabolism: The building up of complex molecules from simpler ones, requiring energy. Examples include protein synthesis and the formation of glycogen from glucose.
* Catabolism: The breaking down of complex molecules into simpler ones, releasing energy. Examples include the breakdown of glucose for energy and the digestion of food.
Metabolism is a complex and highly regulated process that is essential for all living organisms. It allows organisms to obtain energy from their environment, build and repair tissues, and respond to changes in their surroundings.
