Hints
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

Hints
In lactate fermentation, the final electron acceptor is:
| 1. | NAD+ | 2. | pyruvate |
| 3. | O2 | 4. | lactic acid |
