How does penicillin, a beta-lactam antibiotic, kill the bacterial cell?
1.None of the choices
2.block the process of cell wall production by the bacteria
3.affect ribosomes, the cell's protein-building machines
4. cause the strands of DNA to break and prevent the breaks from being repaired.
penicillin and most beta lactan antibiotics act by inhibiting penicillin binding proteins which normally catalyze cross linking of bacterial cell walls.
