multiple choice question\nin anaerobic fermentation pyruvate is reduced to what?\no acetic acid\no…

Brief Explanations:

In anaerobic fermentation, pyruvate is reduced to lactate in lactic - acid fermentation, a common anaerobic process in some cells like muscle cells under oxygen - limited conditions. Acetic acid is not the direct product of pyruvate reduction in typical anaerobic fermentation. Carbonic acid is related to the reaction of carbon dioxide and water and not a product of pyruvate reduction in anaerobic fermentation. Hydrochloric acid is not involved in this process.

Answer:

Lactate
