A nurse assisting a nursing student with medications asks the student to describe how penicillins (PCNs) work to treat bacterial
infections. The student is correct in responding that penicillins: Group of answer choices disinhibit transpeptidases inhibit autolysins. disrupt bacterial cell wall synthesis inhibit host cell wall function
<h3>How does penicillin affect bacterial cell walls?</h3>
Penicillin kills bacteria by inhibiting the proteins which cross-link peptidoglycans in the cell wall .
When a bacterium divides in the presence of penicillin, it cannot fill in the “holes” left in its cell wall.
β-Lactam antibiotics, including penicillins, cephalosporins, monobactams, and carbapenems, are distinguished by a lactam ring in their molecular structure and act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls.
Penicillins work by bursting the cell wall of bacteria. Drugs in the penicillin class work by indirectly bursting bacterial cell walls.
They do this by acting directly on peptidoglycans, which play an essential structural role in bacterial cells.
