Penicillin targets the bacterial cell wall, specifically inhibiting the synthesis of peptidoglycan, a vital component that provides structural integrity to the bacterial cell. By binding to penicillin-binding proteins, it disrupts the process of building the cell wall, leading to a weakened cell wall that ultimately causes the bacteria to burst due to osmotic pressure differences. This particular action of penicillin is especially effective against Gram-positive bacteria like S. pyogenes, which possess a thick peptidoglycan layer. As the cell wall weakens, the bacteria cannot maintain their shape and structural integrity, making them more susceptible to the body's immune response and ultimately leading to their destruction.
