its the process of cellular respiration .
Comparison of Cell and Car An analogy can be drawn between the process of cellular respiration in our cells and a car. The mitochondria are the engines of our cells where sugar is burned for fuel and the exhaust is CO2 and H2O. Note that in a car that burned fuel perfectly, the only exhaust should theoretically be CO2 and H2O also.There are three steps in the process of cellular respiration: a) glycolysis (as described above), b) the Krebs cycle, named after Hans Krebs who figured it out and also known as the citric acid cycle, and c) the electron transport chain. In contrast to fermentation, in the process of cellular respiration, the pyruvic acid molecules are broken down completely to CO2 and a lot more energy is released.

In both cellular respiration and alcoholic fermentation, CO2 is evolved but the enzymes involved are different.
In fermentation mainly zymase, invertase enzymes are involved.
While cellular respiration is a complex phenomena in which a number of enzymes are involved. Ribulose-1,5-bisphosphate carboxylase/oxygenase, commonly known by the abbreviation RuBisCO is the most abundant enzyme in the world. It is an enzyme involved in the first major step of carbon fixation, a process by which atmospheric carbon dioxide is converted by plants to energy-rich molecules such as glucose.
This plays a central role in the process of photosynthesis.
