Fermentation is the biochemical process that occurs when yeast break down glucose. ... This process produces ethanol that is 95% pure. The remaining 5% of the mixture is water.

During which process is ethanol produced quizlet?

Fermentation is a biological process which starts with sugar and yeast and produces ethanol carbon dioxide and energy.

During which process is ethanol produced lactic acid fermentation?

In homolactic fermentation, one molecule of glucose is ultimately converted to two molecules of lactic acid. Heterolactic fermentation, in contrast, yields carbon dioxide and ethanol in addition to lactic acid, in a process called the phosphoketolase pathway.
