Cellular respiration
The anaerobic pathway cellular respiration is known as glycolysis. In glycolysis, glucose molecules are broken down into two pyruvate molecules.Glycolysis is the only stage of cellular respiration which can occur without oxygen. The theoretical yield of adenosine triphosphate (ATP) is 2 molecules for this first stage.
The oxidative phase of the pentose phosphate pathway
The glycolytic pathway is common to both fermentation and cellular respiration. During the course of the metabolic pathway, glucose is broken down to pyruvate. In the presence of oxygen, the pyruvate molecule becomes involved in the TCA cycle. In the absence of oxygen however, fermentation occures. The process is brought about by an enzyme called alcohol dehydrogenase.
