Oxidation of sugars, primarily glucose. Key chemical reactions = REDOX reactions,  transfer of electrons and H +  from one substance to  another. Energy is harvested from electrons and used to  produce ATP. ATP is stored in small quantities in cells but is  primarily produced on demand by cellular  respiration .

2 types of Cellular Respiration Aerobic  - oxygen is used as the final electron acceptor. Anaerobic  – final electron acceptor is an inorganic  molecule; some bacteria and archaea. Fermentation  – is also an anaerobic process.
