Name the enzymes and write the reactions involved in the preparation of ethanol from sucrose by fermentation.

(N/A) The enzymes $Invertase$ and $Zymase$ are used to prepare ethanol from sucrose by fermentation.
Step $1$: Hydrolysis of sucrose into glucose and fructose by $Invertase$.
$C_{12}H_{22}O_{11} + H_{2}O$ $\xrightarrow{\text{Invertase}} C_{6}H_{12}O_{6} (\text{glucose}) + C_{6}H_{12}O_{6} (\text{fructose})$
Step $2$: Conversion of glucose/fructose into ethanol by $Zymase$.
$C_{6}H_{12}O_{6} \xrightarrow{\text{Zymase}} 2C_{2}H_{5}OH + 2CO_{2}$
