Oxygen drives the process of ATP production via ETS. The best explanation for this would be that oxygen:
1. is needed at the end of the aerobic respiration
2. is the terminal electron donor
3. is not required in the glycolytic pathway
4. acts as the final hydrogen acceptor

3. 36 | 4. 38 |
What is the number of ATP molecules produced when pyruvate is converted to lactate by fermentation?
1. 0 | 2. 2 |
3. 4 | 4. 38 |
If fatty acids were to enter the respiratory pathway, they must be converted to a molecule with:
1. | Two carbons | 2. | Three carbons |
3. | Five carbons | 4. | Six carbons |
The respiratory pathway is best described as:
