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.

Answer 2

The intake of antibiotic penicillin kill the bacteria but does not harm human cells. The reason for this type of action of penicillin is just because they(antibiotic) are made with the helpful microbes which cure our diseases and disorders. But overdose of antibiotic will cause side effects.

Hope it helps!

Thanks!
