Fermentation
Fermentation creates energy without the use of oxygen – it is anaerobic. This means that it survives or lives in the absence of free oxygen (air). Fermentation occurs when cells separate the simple sugar, glucose, into a compound called Pyruvate. This process is called Glycolysis . From there, the fermentation can take on 2 different paths. In human muscle cells, the pyruvate is converted into lactate in a simple one step process. The second option occurs when a single celled organism takes the pyruvate and converts it into Carbon Dioxide and Alcohol(Ethanol). This is a two step process. Both methods take place in the absence of oxygen, when oxygen is present NADH which is created through the process of Glycolysis will be transformed back into oxygen, creating more 2NAD+ for the Glycolysis process.
