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.

In humans, albinism (unpigmented skin, hair, and eyes) is due to an enzymatic deficiency, and it is an autosomal recessive trait. Suppose that in a small country of one million people (“Generation 1”), there are 500 aa albinos and 9000 Aa heterozygous carriers. What is the probability that a child will be albino if: Both parents are non-albino members of Generation 2?
