Catabolism – Video

For the related metabolic process, see anabolism. Catabolism (from Greek κατά kata, “downward” and βάλλειν ballein, “to throw”) is the set of metabolic pathways that breaks down molecules into smaller units to release energy. Catabolism breaks down large molecules (such as polysaccharides, lipids, nucleic acids and proteins) into smaller units (such as monosaccharides, fatty acids, nucleotides, and amino acids, respectively). As molecules such as polysaccharides, proteins, and nucleic acids comprise long chains of these small monomer units (mono = one + mer = part), the large molecules are called polymers (poly = many).
