fermentation
Cellular respiration produces CO2 and water as by-products of the metabolic 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.

Cellular respiration is a catabolic process. It involves breaking down complex molecules such as glucose to release energy in the form of ATP.
The first stage of cellular respiration is glycolysis, which occurs in the cytoplasm of cells. This process is thought to be the oldest stage of cellular respiration in evolutionary terms because it is a simple and ancient metabolic pathway that can occur without the presence of oxygen.

glycolysis.
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.
