Detailed explanation-1: -Anaerobic respiration takes place in the absence of oxygen. It is also known as fermentation which converts the sugar to acid, gases and alcohol. In ethanolic fermentation, the pyruvate formed at the end of glycolysis under anaerobic condition forms ethanol and carbon dioxide.

Detailed explanation-2: -Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products.

Detailed explanation-3: -In micro-organisms such as yeast, a uni-cellular (or single cell) fungi, the process of anaerobic respiration is called fermentation. Ethanol, a type of alcohol, and carbon dioxide are produced during this process.

Detailed explanation-4: -Alcohol fermentation, also known as ethanol fermentation, is the anaerobic pathway carried out by yeasts in which simple sugars are converted to ethanol and carbon dioxide.
