Question

What is fermentation? What heppens when grapes ferment? Write the chemical equation.

Answer 1

Fermentation can be defined as a very important metabolic process that takes place in a particular temperature condition wherein an organism carries out the conversion of carbohydrate, such as starch or a sugar, into an alcohol or an acid. eg. Alcohol is formed by conversion of sugar with the help of organism yeast.

The natural yeasts found in rape skins is used to make wine. This yeast converts the sugar into ethyl alcohol which is responsible for it's intoxicating property.

The chemical equation for wine fermentation when starting from glucose is
C6H12O6 = 2CO2 + 2CH3CH2OH, and when starting from maltose or sucrose, it is C12H22O11 = 4CO2 + 4CH3CH2OH. 

Answer 2

Explanation:

fermentation is the process of conversion of sugar in the absence of oxygen into alcohol
