catabolism

The process of breaking down complex biomolecules into simpler ones. For example, the breaking down of glycogen into CO₂ + H₂O. Catabolism is generally accompanied by release of energy in the form of ATP. For more specific examples, see catabolic pathway. A quantitative assessment of catabolism can be measured via calorimetry.
