| the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. |
| cellular respiration n. The series of metabolic processes by which living cells produce energy through the oxidation of organic substances. |
The chemical process that generates most of the energy in the cell, supplying molecules needed to make the metabolic reactions (see metabolism) of an organism run.
Note: The main carrier of energy in metabolism is the molecule ATP.
cellular respiration n.
The series of metabolic processes by which living cells produce energy through the oxidation of organic substances.
cellular respiration
the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining processes and discarding, as waste products, carbon dioxide and water. Organisms that do not depend on oxygen degrade foodstuffs in a process called fermentation.
