Final answer:
Cephalosporins are antibiotics that inhibit bacterial cell wall synthesis by interfering with the synthesis of peptidoglycan, leading to bacterial cell susceptibility to lysis.
Step-by-step explanation:
Among the options provided, Cephalosporins are known as bacterial cell wall synthesis inhibitors. These compounds belong to the β-lactam class of antibiotics which interfere with the synthesis of peptidoglycan, an essential component of the bacterial cell wall. This interference leads to the weakening of the cell wall, making bacterial cells more susceptible to osmotic lysis. On the other hand, Tetracyclines affect protein synthesis, Quinolones inhibit DNA gyrase (affecting DNA replication), and Trimethoprim acts on folate synthesis.
