   ---   Definition of cellular respiration: Respiration is a serial flow of  electrons from an oxidizable substrate (like sugars) to an ultimate  electron acceptor (like oxygen) resulting in the generation of  energy, which is used in various cellular needs.
For these organisms, glycolysis is the first and last step of the cellular respiration process. Glycolysis proceeds normally, as in aerobic conditions, producing a net gain of 2 ATP. The two pyruvate molecules, however, are reduced and the NAD necessary for the initiation of glycolysis is recycled. In this way, the cells do not deplete their store of NAD, although they are only able to produce 2 ATP. As a by-product of fermentation, either ethanol or lactic acid is produced. Cellular respiration is an almost universal process by which organisms utilize the sugars in their food to produce enough energy to perform all the necessary actions of living creatures. Source(s): .
