Penicillin is an enzyme-inhibiting antibiotic that kills bacteria by suppressing the synthesis of bacterial cell walls. The bacterial cell wall is made of cross-linked peptidoglycan, which is synthesized from peptidoglycan monomers by transpeptidase enzymes. How does penicillin suppress the synthesis of bacterial cell walls? O Penicillin binds to the cross-linked peptidoglycan, preventing further bacterial cell wall growth. Penicillin signals the bacterial cell to stop producing the transpeptidase enzymes. Penicillin binds to the transpeptidase enzymes, preventing the synthesis of cross-linked peptidoglycan....

Part A Which of the following statements accurately describes bacterial cell walls? In bacteria with acid-tast cell walls, the carboxylic acid in the walls forms a layer outside a thin layer of hydrophilic polypeptides. The cell walls of gram-negative bacteria contain many more layers of peptidoglycan than those of gram-positive bacteria. In gram-negative bacteria, the thin layer of peptidoglycan is surrounded by an outer membrane made of phospholipids, lipopolysaccharides, and proteins Gram-negative bacterial cell walls contain teichoic acids, whereas the...
