During fermentation, how do changes to a molecule of pyruvic acid to lactic acid or ethyl alchol contribute to the formation of ATP?

Some organisms, such as some bacteria, will undergo lactate fermentation. Two pyruvates are converted to two lactic acid molecules, which ionize to form lactate. In this process two NADH + H+ are converted to two NAD+. Our muscle cells can undergo this process when they are in oxygen debt.
