Anabolic processes in a cell are, in energy terms:

1. Anabolic pathways build large molecules from small ones. 2. The product ends up storing more free energy than the reactants did. 3. If a chemical reaction requires an input of energy rather than releasing energy, its free energy change is positive. 4. Such reactions are called endergonic, and the chemical reactions involved in anabolic processes are endergonic reactions. _Source: OpenStax Biology for AP(R) Courses (CC BY 4.0), Ch 6 'Metabolism', sections 6.1-6.5_
