Anabolism and catabolism are two forms of metabolism, with metabolism being the total of all reactions occurring in a living system (Daempfle, 2016). Anabolism is the series of reactions building complex molecules using stored energy. Photosynthesis is an example of anabolism using energy and raw materials to produce a larger glucose molecule, requiring energy to achieve the process. Catabolism is the reaction that breaks down complex molecules to yield energy. Cellular respiration is a example of catabolism, breaking down a molecule of glucose, releasing the stored energy and occurring spontaneously without net energy or input. Anabolism and catabolism work with each other to perform life functions (Daempfle, 2016).
