Detailed explanation-1: -during anaerobic respiration, yeasts produce alcohol. Glucose is broken down into ethanol and carbon dioxide with the release of energy. Lactic acid is produced in muscles when they respire anaerobically.
Detailed explanation-2: -In yeast, the anaerobic reactions make alcohol, while in your muscles, they make lactic acid.
Detailed explanation-3: -Anaerobic respiration in yeast cells produces carbon dioxide, ethanol and energy.
Detailed explanation-4: -Anaerobic respiration in yeast and plant cells is called alcoholic fermentation, as glucose is broken down to produce ethanol, carbon dioxide, and some ATP. Anaerobic respiration in different microorganisms can be used commercially to produce yoghurt, bread, and alcoholic beverages.
Detailed explanation-5: -Alcoholic fermentation – In this type of anaerobic respiration, glucose is split into ethanol or ethyl alcohol. This process also produces two ATP per sugar molecule. This occurs in yeast and even in some types of fish, such as goldfish.
