Questions
What is the mechanism of action of beta-lactam antibiotics?
Answer: Beta-lactam antibiotics work by inhibiting bacterial cell wall synthesis. They bind to penicillin-binding proteins (PBPs) and prevent the final step of cell wall assembly, causing cell lysis.
Explanation: Without a proper cell wall, bacteria cannot maintain their structural integrity and will burst due to osmotic pressure.
