    What ethanol and carbon dioxide means in Biology A-Level, as defined for AQA.

    Definition of ethanol and carbon dioxide

    Check what you remember

    Read the wording for your board, then hide it and explain ethanol and carbon dioxide in your own words. Rough notes are fine. This is a self-check, with no mark or grade.

    Reference: AQA

    In plants and yeast, pyruvate is decarboxylated to ethanal, releasing carbon dioxide, and ethanal then accepts hydrogen from reduced NAD, forming ethanol.
