Question: Enzymes are typically needed to catalyze reactions that would be very unlikely to occur on their own. Imagine that the activation energy, Ea, for the uncatalyzed cheese reaction at 20C is 18kcal/mol. This reaction could then be catalyzed by colloidial platinum Ea= 13kcal/mol or by the enzyme renin Ea=7kcal/mol. Draw […]

The coat color of mice can be black, white (albino) or agouti. This trait is controlled by two genes – one that controls “agouti” vs “black” coat color (we’ll call this the “coat color gene (locus)”) and one that controls “albino” vs “not albino” (we’ll call this the “albinism gene […]
