Question

Fermentation is the process of ______.
1. Conversion of starch into sugar
2. Conversion of sugar into alcohol
3. Conversion of protein into sugar
4. adding yeast to make wine

Answer 1

Correct Answer - Option 2 : Conversion of sugar into alcohol

The correct answer is Conversion of sugar into alcohol.

• Fermentation is the process by which molecules such as glucose are broken down anaerobically.
• By the process of fermentation, the sugars are converted into alcohol.
• The enzymes like pyruvic acid decarboxylase and alcohol dehydrogenase catalyze these reactions.
• It normally occurs in yeast cells bacteria and in the muscles of animals.
• It is a method of extracting energy from molecules.
• Fermentation accounts for only a partial breakdown of glucose.
• In fermentation, there is a net gain of only two molecules of ATP for each molecule of glucose degraded to pyruvic acid.
• Wine and beer are produced by fermentation.
• No ATP would be produced without fermentation.
