Assertion : Fermentation is incomplete oxidation of glucose.
Reason: In fermentation, glucose may be converted to $\mathrm{CO}_2$ and ethanol.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Solution
- Assertion: Fermentation is incomplete oxidation of glucose.
- This statement is true. During fermentation, glucose is not fully oxidized to carbon dioxide and water as it would be in aerobic respiration. Instead, the process stops at intermediate products like ethanol, lactic acid, or other organic compounds, making it an incomplete oxidation.
- Reason: In fermentation, glucose may be converted to \(\mathrm{CO}_2\) and ethanol.
- This statement is also true. In alcoholic fermentation (e.g., in yeast), glucose is broken down to ethanol and carbon dioxide.
Correct Relationship Between Assertion and Reason:
The reason correctly explains the assertion because the production of ethanol and \(\mathrm{CO}_2\) demonstrates that glucose is not completely oxidized, but instead converted to intermediate products.
Correct Answer:
(1) If both assertion and reason are true and reason is the correct explanation of assertion.
