Detailed explanation-1: -Water is not produced during anaerobic respiration in unicellular fungus-like yeast. Here, the glucose is incompletely oxidised to form ethanol (C2H5OH) and Carbon dioxide (CO2).

Detailed explanation-2: -Respiration can be of three types depending on the availability of oxygen. Aerobic respiration occurs in the abundance of oxygen in mitochondria and its end products are carbon dioxide and water. Anaerobic respiration occurs in absence of oxygen in yeast cells and its end products are carbon dioxide and ethyl alcohol.

Detailed explanation-3: -Hint: Alcohol (ethyl alcohol) is the by-product that occurs during the glycolysis process in the absence of oxygen and presence of yeast. It is one type of cellular respiration which is also called a fermentation process.

Detailed explanation-4: -Anaerobic respiration is a type of cellular respiration where respiration takes place in the absence of oxygen. The end product of anaerobic respiration in plants is ethanol.

Detailed explanation-5: -Ethanol is produced by anaerobic fermentation of glucose by Saccharomyces cerevisiae.
