Why are fermentation reactions important for cells? A) They utilize oxygen. B) They regenerate NAD⁺so that glycolysis can continue. C) They generate oxygen. D) They produce alcohol used in alcoholic beverages.

Question

Quizplus · Accepted Answer

Fermentation reactions are important for cells as they regenerate NAD+ so that glycolysis can continue. Without fermentation, glycolysis would come to a halt due to a lack of NAD+ to accept electrons from glucose during the process. Therefore, cells rely on fermentation to keep producing ATP through glycolysis even in the absence of oxygen. Choices A, C, and D are incorrect as fermentation reactions do not utilize or generate oxygen or produce alcohol as a primary function.
