In lactate fermentation, the final electron acceptor is:
| 1. | NAD+ | 2. | pyruvate |
| 3. | O2 | 4. | lactic acid |
Yeast cells are able to regenerate regenerated from NADH during the :
1. reduction of acetaldehyde to ethyl alcohol
2. oxidation of pyruvate to acetyl CoA
3. reduction of pyruvate to form lactate
4. oxidation of NAD+ in the citric acid cycle

When oxygen is not available to a cell, NADH formed during glycolysis:
| 1. | does not undergo any change as there is no need for the cell to regenerate NAD+ |
| 2. | passes electrons to the electron transport system |
| 3. | passes hydrogen atoms to pyruvic acid |
| 4. | passes electrons and hydrogen atoms to acetyl coA |
What would be true when comparing the processes of anaerobic respiration and fermentation?
I. Both processes do not use oxygen.
II. An electron transport chain is used in anaerobic respiration but not in fermentation.
| 1. | Only I | 2. | Only II |
| 3. | Neither I nor II | 4. | Both I and II |
| Assertion (A): | The maximum concentration of alcohol in beverages that are naturally fermented with yeast is about 13%. |
| Reason (R): | In alcohol fermentation, yeast converts pyruvic acid to ethanol and carbon dioxide. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
