Question

The end product of a process is ethanol and carbon dioxide with the release of energy. Name this process and write the pathway involved in the reaction.

Answer 1

During aerobic respiration, the product is CO₂ & H₂O. While during anaerobic respiration, the product can be either lactic acid or ethanol+CO₂ on the basis of enzyme involved. 

If the product is ethanol &CO₂, the process is termed as Fermentation. 

Initially glucose gets converted into pyruvic acid (by the process of glycolysis-common in both aerobic & anaerobic respiration). In fermentation, this pyruvic acid produces ethanol & carbon-dioxide in the presence of enzyme alcohol dehydrogenase. This fermentation process is also used for industrial production of alcohol.
