As you all know, cellular respiration is one of the, if not the, most important process that goes on in our bodies and other animals' bodies today. Cellular respiration is the process that is opposite from photosynthesis. While plants are taking in carbon dioxide and water to make sugar and oxygen, cellular respiration uses the oxygen and sugar o make carbon dioxide, water and 36 ATP. The three "mini processes" that take place during cellular respiration are glycolysis, oxidative respiration, and the electron transport chain. Fermentation also occurs in some cases where there is no oxygen present. Glycolysis is the first stage in cellular respiration.
It starts with pyruvate, the end product of glycolysis. Either ethanol a fancy name for alcohol or lactate lactic acid can be produced form the fermentation of pyruvate depending on the organism. CO2 released during fermentation, all ATP is produced during glycolysis. In summary cellular respiration can be anaerobic or aerobic respiration.
