Anaerobically (in absence of oxygen), yeast cells may obtain energy by fermentation, resulting in the production of ATP, CO2 AND ETHANOL. This is called ethanol fermentation or alcoholic fermentation where sugars such as glucose, fructose, and sucrose is converted into cellular energy (ATP), producing ethanol and carbon dioxide as by products.
Producers use energy from the sun to create glucose (b), or usable chemical energy
