Cytosolic pyruvate is the end product of glycolysis. Its fate depends on the metabolic status of the cell. If there is plenty of oxygen, the aerobic pathway dominates. If oxygen is insufficient, the anaerobic pathway dominates. Associate each of the following characteristics with either the aerobic or anaerobic fate of pyruvate.
| Catalyzed by lactate dehydrogenase | |
| Catalyzed by pyruvate dehydrogenase complex | |
| Oxidizes NADH | |
| Oxidizes pyruvate | |
| Produces acetyl CoA | |
| Produces lactate | |
| Recycles NADH to NAD+ | |
| Redirects glucose oxidation to the mitochondrion | |
| Reduces NAD+ | |
| Reduces pyruvate |
