why cant oxidation of glucose to pyruvate be the final stage in glucose catabolism? what could be the outcome of pyruvate if a cell goes through fermentation?
Added by Julie P.
Step 1
Step 1: The oxidation of glucose to pyruvate cannot be the final stage in glucose catabolism because pyruvate still contains a significant amount of energy that can be further extracted through additional metabolic pathways. Show more…

Explain why pyruvate cannot be converted to glucose in an exact reverse of the glycolysis pathway.
Dr. Satish I.
Why does glucose oxidation occur in a series of steps? It doesn't have to; it just happens to be that way. Glucose cannot pass into the mitochondria and oxygen cannot enter the cytosol. Glycolysis evolved first and steps were just added over time. One step wouldn't allow the energy released to be harnessed efficiently. Glucose is reduced, not oxidized.
Rupsa S.
In the conversion of glucose into two molecules of lactate, the NADH generated earlier in the pathway is oxidized to $\mathrm{NAD}^{+} .$ Why is it not to the cell's advantage to simply make more $\mathrm{NAD}^{+}$ so that the regeneration would not be necessary? After all, the cell would save much energy because it would no longer need to synthesize lactic acid dehydrogenase.
