Which mechanism accounts for Amoxicillin├óÔé¼Ôäós antibacterial action?
Correct answer
A
Rationale
Amoxicillin, a broad-spectrum beta-lactam antibiotic, kills bacteria by inhibiting the transpeptidation reaction in bacterial cell wall synthesis. It binds to penicillin-binding proteins, preventing the formation of cross-links in the peptidoglycan layer, leading to cell lysis and death. The resolution of fever and sore throat after therapy demonstrates successful bacterial eradication. Amoxicillin├óÔé¼Ôäós mechanism differs from agents that inhibit protein or nucleic acid synthesis, which underscores its role in treating respiratory and ENT infections caused by susceptible bacteria.
