I: | ATP is produced |
II: | ATP is used |
III: | Glucose is partially oxidised |
Assertion (A): | Fermentation is a type of anaerobic respiration where glucose is partially oxidized to produce energy. |
Reason (R): | Fermentation results in the production of ethanol or lactic acid without the use of oxygen. |
1. | Both (A) and (R) are True and (R) correctly explains (A). |
2. | Both (A) and (R) are True but (R) does not correctly explain (A). |
3. | (A) is True, (R) is False. |
4. | (A) is False, (R) is True. |
The maximum concentration of alcohol in beverages that are naturally fermented is about:
1. 5 – 8 % | 2. 13 – 15 % |
3. 33 – 34 % | 4. 47 – 49 % |
What is the number of ATP molecules produced when pyruvate is converted to lactate by fermentation?
1. 0 | 2. 2 |
3. 4 | 4. 38 |
Consider the given statements:
Statement I: | In alcohol fermentation in yeast, pyruvic acid decarboxylase and alcohol dehydrogenase convert pyruvic acid to carbon dioxide and ethanol. |
Statement II: | In lactic acid fermentation, lactate dehydrogenase reduces pyruvic acid to lactic acid and carbon dioxide in muscle cells during exercise. |
1. | Both Statement I and Statement II are correct |
2. | Both Statement I and Statement II are incorrect |
3. | Statement I is correct but Statement II is incorrect |
4. | Statement I is incorrect but Statement II is correct |
The products of fermentation do not include:
1. | CO2 | 2. | O2 |
3. | ethanol | 4. | lactate |
