What is anabolic metabolism?

Anabolic metabolism is the set of biosynthetic reactions that build complex molecules from simpler ones, and it requires energy input to form the new chemical bonds. In cells, these pathways use energy carriers like ATP and reducing power such as NADPH to assemble larger structures, and the resulting molecules store energy in their bonds. Examples include making proteins from amino acids, nucleic acids from nucleotides, fatty acids and lipids from smaller precursors, and polysaccharides from glucose. This is opposite to catabolic metabolism, which breaks down large molecules to release energy. So describing synthesis of complex molecules from simpler ones with energy storage captures what anabolic metabolism is.
