Anabolism, as in âanabolic steroidsâ, refers to those metabolic processes that utilize energy to biosynthesize complex molecules and to generate growth. The reverse process is catabolism, whereby nutrients are broken down to release energy. Catabolic processes provide intermediates for synthetic or further catabolic pathways and release energy, usually as the energy carrier molecules ATP and NADPH. The following mnemonic may help in remembering the difference: A B C D : Anabolism = Biosynthesis ; Catabolism = Degradation.
