Sulfonamides inhibit an enzyme necessary for production of purines and pyrimidines. what long-term impact would it have on a microbe if it were grown in the presence of sulfonamides?

The cell would cease to divide

If the enzyme that necessary for purines and pyrimidines production inhibited, the replication process for both of them would be halt. Purine and pyrimidine is needed in genetic material synthesis. Cell division involve a replication of genetic material. Since the genetic material couldn't be synthesized, cell division could not be done.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
