Fermentation - Definition, Types, Equation and Products Biology

WebFermentation is a metabolic process that occurs in the absence of oxygen and is used by cells to generate energy from glucose. This process can occur in a variety of organisms, including yeast, bacteria, and human muscle cells. Fermentation occurs when there is no oxygen available for the cells to use in the process of cellular respiration. WebIn fermentation, the only energy extraction pathway is glycolysis, with one or two extra reactions tacked on at the end. Fermentation and cellular respiration begin the same way, with glycolysis.
