Answer:
Penicillin binds and inhibits bacterial enzyme DD-transpeptidase.
Explanation:
Penicillin is made up of 4 rings of β-lactam and acts by binding to DD-transpeptidase of bacteria. The DD-transpeptidase facilitates the cross-linking of the peptidoglycan cell wall of bacteria. This leads to malformation of the protective cell wall of the bacteria and causes it to lyze and die.
