How do the antibiotics called cell wall inhibitors works specifically? , and why can't they be used on animals cells?

Answer & explanation:

Cell wall inhibitors are the bactericides that interfere with the synthesis of peptidoglycan, a polymer made up of sugars and amino acids that form a mesh on the outside of the bacterial cell membrane, so peptidoglycan is primarily responsible for bacterial cell wall formation.

As a consequence of peptidoglycan inhibition, cell wall weakening occurs, and the cell undergoes lysis (breakdown).

The best known cell wall inhibitor antibiotic is penicillin, which has low toxicity and therefore attacks bacterial cells, but will hardly affect host cells, since animal cells lack peptidoglycan.
