Does anaerobic respiration in animals produce ethanol?

In anaerobic respiration, the end-products are ethanol and carbon dioxide in plants whereas the end-products are lactic acid only in animals.

What happens to ethanol in anaerobic respiration?

Anaerobic conditions in yeast convert pyruvate to carbon dioxide and ethanol. This occurs with the help of the enzyme pyruvate decarboxylase which removes a carbon dioxide molecule from the pyruvate to yield an acetaldehyde.

Does ethanol fermentation occur in animals?

Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of animals. ... However, when the percentage of ethyl alcohol reaches approximately 15 percent, the alcohol kills the yeast cells.
