How will the prescribed penicillin kill S. pyogenes that is causing Shelly's infection? View Available Hint(s) Penicillin will attach to bacterial ribosomes and inhibit protein synthesis, which will lead to the death of S. pyogenes. Penicillin will interfere with peptidoglycan synthesis, ultimately weakening the cell wall and leading to cellular lysis. Penicillin will disrupt the outer membrane, leading to a loss of structural integrity and death of S. pyogenes. Penicillin will poke holes in the plasma membrane, weakening the cell and leading to cellular lysis.

Penicillin works its magic by targeting the synthesis of peptidoglycan, a vital component of bacterial cell walls. S. pyogenes, like many bacteria, relies on a strong cell wall to maintain its shape and protect against environmental stresses. When penicillin interferes with this synthesis, the wall becomes weak, and the bacterium cannot hold its shape, resulting in lysis or bursting. This mechanism is why penicillin is so effective; it differentiates between bacterial cells and human cells, meaning it can wipe out those pesky bacteria while leaving Shelly's own cells unharmed. It’s a classic case of a targeted attack on the invaders, ensuring she recovers from her infection!
