In the conversion of carbonic acid (H2CO3) to carbon dioxide or carbonic acid gas (CO2) with heat, molecular hydrogen (H2) is released. Therefore a kind of vacuity is created, causing a reduction in the inner 'volume'. — Ed.

Metabolism ("change") is the set of life-sustaining chemical reactions in organisms. The three main purposes of metabolism are:
(1) the conversion of the energy in food to energy available to run cellular processes;
(2) the conversion of food to building blocks for proteins, lipids, nucleic acids, and some carbohydrates;
(3) and the elimination of metabolic wastes. [Metabolism]
