What effect does penicillin have on bacteria?

Penicillin kills bacteria by binding from the beta-lactam ring to DD-transpeptidase, inhibiting their interconnection activity and preventing the reformation of the cell wall. Without a cell wall, a bacterial cell is vulnerable to outside water and molecular pressures and dies quickly.
