Alcoholic Pyruvate Ethanal Explain Fermentation Step Converted Catalysed

In alcoholic fermentation, pyruvate is converted to ethanal by pyruvate decarboxylase, and then ethanal is reduced to ethanol by accepting hydrogen from NADH, regenerating NAD.

Front Explain alcoholic fermentation step by step.
Back Alcoholic fermentation:
  • Pyruvate is converted to ethanal - catalysed by pyruvate decarboxylase
  • Ethanal is reduced - accepts hydrogen from NADH, becoming ethanol
  • NAD is regenerated
