When an organism is exposed to a limited quantity of oxygen, the cell's mitochondria will stop cellular respiration involving the Krebs cycle and enter the process of fermentation to survive. What conclusion can be drawn regarding an organism's ability to undergo fermentation?

Fermentation makes more ATP than the cellular respiration.

Fermentation does not require food.

Fermentation uses more ATP than it is able to produce.

Fermentation must create a net gain of ATP.

Fermentation makes more ATP than the cellular respiration. - It does not.
Fermentation does not require food. - It requires food just as cellular respiration.
Fermentation uses more ATP than it is able to produce - It does produce less ATP but it does not use more than it produces.

In conclussion: Fermentation must create a net gain of ATP.
