Fermentation.
When no oxygen is present cells use fermentation to regenerate NAD+ so glycolysis can continue (e.g., lactic acid fermentation in muscle cells or alcoholic fermentation in yeast). The electron transport chain (and thus the Krebs cycle in typical aerobic cells) requires oxygen as the final electron acceptor.
