It can be prepared by the fermentation of sugar (e.g., from molasses), which requires an enzyme catalyst that is present in yeast; or it can be prepared by the fermentation of starch (e.g., from corn, rice, rye, or potatoes), which requires, in addition to the yeast enzyme, an enzyme present in an extract of malt.

Answer 2

Answer:

Ethanol is a liquid alcohol. It can be used like gasoline in vehicles with internal combustion engines. These engines compress liquid fuel and ignite it with a spark. This creates a combustion reaction, which releases energy. Internal combustion engines capture that energy to power the vehicle.
