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 |
| 1. | substrate-level phosphorylation |
| 2. | chemiosmosis |
| 3. | Krebs cycle |
| 4. | Pyruvate decarboxylation |
| Statement I: | Succinate dehydrogenase is an enzyme complex found in the inner mitochondrial membrane of eukaryotes. |
| Statement II: | Succinate dehydrogenase is the only enzyme that participates in both the citric acid cycle and the electron transport chain. |
| 1. | Statement I is correct; Statement II is correct |
| 2. | Statement I is incorrect; Statement II is correct |
| 3. | Statement I is correct; Statement II is incorrect |
| 4. | Statement I is incorrect; Statement II is incorrect |
