8. yeasts

9.  alcohol

10. ethyl

Explanation:

In fermentation, energy is obtained from organic compounds without the need of oxygen, that's why it's called an anaerobic process. This process usually starts pyruvic acid, which is a product of glycolysis, which with help of a specific enzyme takes electrons from NADH and is transformed into another molecule, depending on the type of fermentation. In alcoholic fermentation, it's transformed into ethanol (also called ethyl alcohol), whereas in lactic fermentation it's transformed into lactic acid. Yeasts are unicellular organisms that perform alcoholic fermentation.
