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 |
