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?
A. Fermentation makes more ATP than the cellular respiration.
B. Fermentation does not require food.
C. Fermentation uses more ATP than it is able to produce.
D. Fermentation must create a net gain of ATP.

Well, how about we start with some elimination.

kaibeth · Answer

D? because you have to produce a certain amount of ATP?

NerdyLizard · Answer

Why should it be removed?

NerdyLizard · Answer

It is the only one that makes sense.

kaibeth · Answer

and thank you!
