Answer 3

From Wikipedia:
'Zymase is an enzyme complex ("mixture") that catalyzes the fermentation of sugar into ethanol and carbon dioxide.'
http://en.wikipedia.org/wiki/Zymase

You get the following chemical reaction:\[sugar\space(glucose) \space \xrightarrow{zymase}\space ethanol+CO_2\]
Glucose is the reactant, zymase is the catalyst, and ethanol is one of the products. Water is probably close by.
