Yeast will normally convert pyruvate to ethanol. Why is this better for the yeast than a conversion to lactate?

#Unit 1. Molecules and their Interaction Relevant to Biology
  1. Conversion to ethanol releases more NAD+ per mole than the conversion to lactate.

  2. The carbon atoms are more oxidized in ethanol than in lactate.

  3. Ethanol is neutral, but lactate production is accompanied by a sharp decrease in pH.

  4. Ethanol production is not better. Yeast normally produces ethanol and lactate in equilmolar amounts.
