Summary Introduction
Introduction:
Fermentation is an anaerobic process by which a cell produces energy by the breakdown of sugar in the absence of oxygen. It takes place in the bacteria, yeast and the cells that lack oxygen like during vigorous exercise. The glycolysis in fermentation produces two ATP, two NADH and two pyruvate molecules.
