Enzymes involved in the preparation of ethanol from sucrose by fermentation

The enzymes used in the fermentation process for converting sucrose into ethanol are invertase and zymase.
Invertase converts sucrose into glucose and fructose. Then, glucose and fructose undergo fermentation in the presence of zymase to form ethanol.

Reaction involved in the preparation of ethanol from sucrose by fermentation:

Following are the reactions involved in the preparation of ethanol from sucrose by fermentation:

$C_{12} H_{22} O_{11} + H_{2} O I n v e r t a s e - ----- \to C_{8} H_{12} O_{8} + C_{8} H_{12} O_{8}$
Sucrose Glucose Fructose
$C_{8} H_{12} O_{8} Z y m a s e - ---- \to 2 C_{2} H_{6} O H + 2 C O_{2}$
Glucose/Fructoes Ethanol
