Cell wall synthesis inhibitors primarily work by:

• A. Stop production of cell wall components
• B. Inhibit ribosomal protein synthesis
• C. Disrupt DNA replication
• D. Disrupt RNA transcription

Answer: (C)

Cell wall synthesis inhibitors work by blocking the construction of the peptidoglycan layer that gives bacterial cells their shape and rigidity. They target the enzymes that form the peptidoglycan scaffold or cross-link the sugar-peptide chains, so the cell wall cannot properly assemble. This weakens the wall and, during growth and division, the bacteria can lyse from osmotic pressure. Classic examples include antibiotics that bind penicillin-binding proteins and prevent cross-linking, as well as those that interfere with the addition or transport of cell wall precursors. Because of this mode of action, these drugs affect cell wall formation rather than ribosome function, DNA replication, or RNA transcription, which are the targets of other antibiotic classes.
