Anabolic reactions build new molecules and/or store energy. The energy of catabolic reactions is used to drive anabolic reactions. The energy for chemical reactions is stored in ATP. Often when I ask students What is ATP the answer they give is Energy.
The energy released in respiration is used to synthesize ATP to store this energy. The energy stored in ATP can then be used to drive processes requiring energy, including biosynthesis, locomotion or transportation of molecules across cell membranes. Because of its ubiquity in nature, ATP is also known as the universal energy currency.
