ACS Biochemistry Exam Questions With Complete Solutions Metabolism (catabolism and anabolism) - ANSWERS Metabolism: sum of total chemical reactions in an organism, also the method by which cells extract and use energy from their environment. Catabolism: The process by which stored nutrients and ingested foods are converted to a usable form of energy. It produces simple products CO2, H2O, NH3, and building blocks such as sugars and fats that are used in anabolism. Anabolism: t...
