Answer:
The correct answer is "cell wall".
Explanation:
Lysozyme and the antibiotic penicillin have similar mechanisms of action because both cause damage to the bacterial cell wall. Lysozyme binds to the peptidoglycan molecules of the cell wall and catalyzes the hydrolysis of the 1,4-beta-linkages of its subunits. Penicillin binds to the beta-lactam ring to DD-transpeptidase in bacteria that is reproducing, inhibiting the cell wall formation.
