What is Fermentation (Anaerobic Respiration)?
Fermentation, also known as anaerobic respiration, is the type of cellular respiration that occurs without oxygen. It is far less efficient than aerobic respiration and usually only occurs when oxygen levels are depleted. There are two different processes of fermentation. In plants and yeasts glucose is broken down to produce ethanol and carbon dioxide and release energy. In animals glucose is broken down to produce lactic acid and release energy. See the video for the full chemical equations for each process. The energy released from fermentation is used to fuel the ATP cycle which then provides energy for the cells work.
