The anaerobic process where cells convert pyruvic acid into carbon dioxide and ethyl alcohol is called alcoholic fermentation.

Here's a breakdown:

* Anaerobic: This means the process occurs in the absence of oxygen.

* Pyruvic acid: This is a key intermediate molecule in cellular respiration.

* Carbon dioxide: A waste product of the process.

* Ethyl alcohol (ethanol): The primary end product of alcoholic fermentation.

This process is primarily carried out by certain types of yeast and bacteria. It's crucial in the production of alcoholic beverages like beer, wine, and sake.
