Alcohol fermentation

This process is present in yeasts and some bacteria with the purpose of providing anaerobic energy to these unicellular organisms, in the absence of oxygen. In this process, energy is obtained by dissociating glucose molecules and generating alcohol and carbon dioxide waste.

Therefore, the correct answer to this question is option A. Yeasts and some bacteria.
