Answer 1

Answer:

Antibiotic work by affecting things that bacterial cell have but human cell don't.

eg:- human cell do not have cell walls while many types of bacteria do.

Answer 2

Human cells do not make or need peptidoglycan. Penicillin, one of the first antibiotics to be used widely, prevents the final cross-linking step, or transpeptidation, in assembly of this macromolecule. The result is a very fragile cell wall that bursts, killing the bacterium.
