What is the difference between anabolism and catabolism?
Metabolism comprises two opposing processes: anabolism and catabolism. Anabolism is a set of synthesis reactions that transform simpler compounds into organic molecules in general with energy spending. Catabolism is a set of reactions that break organic molecules into simpler and less difficult substances in general with liberation of energy. The energy liberated in catabolism might be used in vital processes of the organism, containing anabolism.
