Fact 1: Ethanol is produced by alcoholic fermentation of the glucose in corn or other plants.

Fact 2: Ethanol depresses neuronal excitability.

Given the two facts above, answer the question "what effect does alcoholic fermentation of the glucose in corn or other plants have?" with the following options: 
- kills people
 - depress neuronal excitability
 - it helps plants in growing
 - negative impact
 - corn on the cob
 - changes density
 - Generating heat
 - Plant growth is reduced


 

  depress neuronal excitability
