glycolysis still occurs as it is anaerobic itself - in the cytoplasm
only 2 ATP produced per glucose as only glycolysis occurs
lactate fermentation
mammals
pyruvate -> lactate (lactic acid)
NADH used to form NAD, which is then used again in glycolysis so small amounts of ATP is still produced
lactate fermentation
cells can tolerate high levels of lactic acid for short periods of time
lactate is removed from cells, through the blood stream and to the LIVER
the liver converts it back to glucose in gluconeogenesis
alcoholic fermentation (yeast)
pyruvate is decarboxylated to form ethanal
ethanal is reduced to form ethanol, using NADH from glycolysis to produced NAD, which is used again in glycolysis so small amounts of ATP is still produced
