Fermentation is inefficient in using the energy found in food molecules and the resulting alcohol can be toxic to the organism producing it. Which of the following is a reason why an organism would utilize fermentation?
A) Fermentation helps to recycle NAD+ molecules and allows glycolysis to proceed with ATP production.
B) The organism can survive short spells of anaerobic conditions and maintain growth and reproduction.
C) Fermentation can provide a rapid burst of ATP since it does not have to go through the full breakdown cycle.
D) For very small organisms, fermentation can be a simple process and is less complicated than cellular respiration.
E) All of the answer choices are reasons organisms would utilize fermentation.

Fermentation is a metabolic process that allows organisms to produce energy under anaerobic conditions. It recycles NAD+ to permit continued ATP production via glycolysis (A), supports survival in oxygen-limited environments (B), offers a quick ATP supply without the need for oxygen or a complete breakdown of glucose (C), and is less complex than aerobic respiration, making it suitable for small organisms (D).
