RESPIRATION &#151;(Biology) The oxidative process occurring within living cells by which the chemical energy of organic molecules (i.e., substances containing carbon, hydrogen, and oxygen) is released in a series of metabolic steps involving the consumption of oxygen (O 2 ) and the liberation of carbon dioxide (CO 2 ) and water (H 2 O).
