Respuesta :

The answer is choice A. 

Answer: The given statement is true.

Explanation:

When there occurs changes in organic substrates with the help of enzyme action then this process is known as fermentation. This process results in the formation of alcohols.

For example, process of fermentation occurs in yogurt, pickles, beers, wine etc.

Also equation for alcoholic fermentation is as follows.

      [tex]C_{6}H_{12}O_{6} \rightarrow 2C_{2}H_{5}OH + 2CO[/tex]

Therefore, we can conclude that the given statement process by which complex compounds are broken down by enzymes and by which many organic alcohols are formed is called fermentation, is true.
