Question

Quizplus · Accepted Answer

During fermentation, yeast cells consume sugar molecules and convert them into energy, carbon dioxide and alcohol. Carbon dioxide is released as a waste product and can be seen as bubbles in the fermentation process. Therefore, the best choice is C, as it correctly identifies carbon dioxide and alcohol as the waste products of fermentation. Option A is incorrect because oxygen is not a waste product of fermentation, and option B is incorrect because carbon monoxide is not produced in significant amounts during fermentation. Option D is incorrect because nitrogen is not produced as a waste product during fermentation.
