How do sulfa drugs selectively kill bacteria while causing no harm to humans?
A.Folic acid is a vitamin required for the synthesis of a coenzyme needed to make
the amino acid methionine and the purine and pyrimidine nitrogenious bases for
DNA and RNA and folic acid is produced by humans.
B.Sulfa drug binds to the enzyme, no product is formed, folic acid is made and the
biosynthesis of methionine and nitrogenous bases increases.
C.Humans are not harmed because they do not synthesize their own folic acid. It
is obtained in the diet.
D.None of the above
