In alcoholic fermentation Pyruvic acid is broken down into?
Correct answer: C. Ethyl alcohol
- A. Acetaldehyde
- B. Methyl alcohol
- C. Ethyl alcohol
- D. Lactic acid
Explanation
In alcoholic fermentation, pyruvic acid first loses carbon dioxide to form acetaldehyde, which is then reduced to ethyl alcohol. The likely distractor is lactic acid, because it is also produced from pyruvate, but that occurs in lactic acid fermentation rather than alcoholic fermentation.
