Quizplus · Accepted Answer

Fermentation of glucose always begins with glycolysis, which produces pyruvic acid as a substrate for fermentation. However, the end product varies depending on the type of fermentation and the organism carrying out the process. Some common end products include ethanol, lactic acid, and acetic acid. Option A is incorrect because the end product of fermentation varies. Option C is incorrect because different fermentation reactions produce different end products.
