Question

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.

Answer 1

Fermentation must create a net gain of ATP.

Step-by-step explanation:

Fermentation is a process in which organisms such as yeast, bacteria convert sugar into an alcohol or an acid. It is an anaerobic process because it does not require oxygen. The fermentation process is completed in the cytoplasm with a net gain of 2ATP during the glycolysis. Although it is a common pathway it is not the only method used by organisms produce ATP anaerobically.

Answer 2

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, it means Fermentation must create a net gain of ATP.
