Analyze the biochemical differences between alcohol fermentation and lactic acid fermentation.

Alcohol fermentation requires oxygen, while lactic acid fermentation does not.

Alcohol fermentation involves decarboxylation of pyruvate, while lactic acid fermentation involves direct reduction of pyruvate.

Alcohol fermentation produces lactate, while lactic acid fermentation produces ethanol.

Alcohol fermentation occurs in muscle cells, while lactic acid fermentation occurs in yeast.
