Question

Fermentation is an:

• A. Exothermic reaction
• B. Endothermic reaction
• C. Reversible reaction
• D. None of these

Answer 1

The correct option is A

Exothermic reaction

Explanation of the correct option:

Option A is correct:

Fermentation: - It is a chemical process by which molecules such as glucose are broken down in the absence of oxygen.

Example: Wine and beer are made by fermentation process.

Properties of fermentation:

1. Fermentation is an incomplete oxidation of glucose under anaerobic conditions
2. It is an exothermic reaction.
3. It releases heat to surroundings.

Explanation of the incorrect options:

Options B, C, and D:

1. Fermentation is not an endothermic reaction as it does not absorb heat.
2. It is not reversible.

Hence, option A is correct.
Fermentation is an exothermic process.
