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: -Anaerobic respiration can be either alcoholic fermentation (that produces alcohol and carbon dioxide) or lactic acid fermentation (that produces lactic acid). Either form of anaerobic respiration does not produce any water molecules.

Detailed explanation-3: -Aerobic respiration uses oxygen. Anaerobic respiration is respiration without oxygen; the process uses a respiratory electron transport chain but does not use oxygen as the electron acceptors.
