Can you explain why?

aaronq · Answer

Alcoholic fermentation occurs in yeast cells.

Lactic acid fermentation occurs in muscle cells after they've been depleted of $O_2$ - the final electron acceptor in the electron transport chain. Muscle cells resort to anaerobic (no-oxygen) respiration to re-oxidize NADH to $NAD^+$ in order to be able to continue with glycolysis.

Both, alcoholic and lactic acid fermentation, are types of anaerobic respiration.
