| Back | - irreversible unlike lactate fermentation, pyruvate converted to ethanal catalysed by pyruvate decarboxylase, ethanal then accepts H atom reduced NAD (now ethanol), regenrated NAD continues to act as coenzyme and glycolysis continues, not short term process and continues indefinately in O2 abdence, ethanol toxic waste product to yeast cells and unable to survive if ethanol levels high |
