Bacitracin directly attacks the peptide cross-links. True or False?

False.
Bacitracin does not directly attack the peptide cross-links. Instead, Bacitracin interferes with the dephosphorylation of the lipid carrier molecule (bactoprenol) that transports the building blocks of the peptidoglycan bacterial cell wall outside of the inner bacterial membrane. This action disrupts the synthesis of the cell wall, but it does not directly target the peptide cross-links within the cell wall.
