Cell wall synthesis
Explanation:
Antibiotics are the compounds that work against bacteria and kills bacteria or slow their growth. Every antibiotic have their own mode of action. Beta-lactam antibiotics like penicillin and cephalosporins work on cell wall synthesis.
They stop the synthesis of peptidoglycan by inhibiting the transpeptidation reaction.
