anabolism definition. The chemical reactions that synthesize molecules in metabolism. (Compare catabolism.) Note: Athletes often attempt to improve their performance by speeding up this molecule-building process through the use of drugs called anabolic steroids, despite the potential health risks involved.
Catabolism is the sum of all the metabolic processes by which complex molecules are broken down to simpler ones. This includes the processes by which molecules are broken down to yield cellular energy. Anabolism is just the opposite.
