Why is fermentation important in animals? A) It is the best reaction we can utilize to produce ATP. B) It produces lactate, which is essential for animals. C) It produces carbon dioxide, which is necessary for our cells. D) It generates the NAD⁺ we need for metabolism. E) It helps to recycle NAD⁺ molecules and allows glycolysis to proceed with ATP production.

Question

Quizplus · Accepted Answer

Fermentation helps to recycle NAD+ and allows glycolysis to continue producing ATP. This is important because glycolysis is the only source of energy for many cells, including red blood cells, and NAD+ is necessary for it to continue functioning. Additionally, fermentation helps to generate ATP in the absence of oxygen, which can be important during times of strenuous exercise when oxygen availability is limited.
