Penicillin inhibits the synthesis of bacterial cell walls by targeting the enzymes involved in their production, which are specific to prokaryotic cells. In contrast, eukaryotic cells have different cell wall structures and are not affected by penicillin. This makes penicillin selectively toxic to bacteria, making it an effective antibiotic while sparing eukaryotic cells.
