Anabolism - Wikipedia - cellular respiration  ## Metadata - Author: **cellular respiration** - Full Title: Anabolism - Wikipedia - Category: #articles - URL: https://en.wikipedia.org/wiki/Anabolism ## Highlights - Polymerization, an anabolic pathway used to build macromolecules such as nucleic acids, proteins, and polysaccharides, uses condensation reactions to join monomers. Macromolecules are created from smaller molecules using enzymes and cofactors. - Tags: #chemistry - Anabolism (/əˈnæbəlɪsm/) is the set of metabolic pathways that construct molecules from smaller units.[1] These reactions require energy, known also as an endergonic process.[2] Anabolism is the building-up aspect of metabolism, whereas catabolism is the breaking-down aspect. Anabolism is usually synonymous with biosynthesis
