Macmillan Learning Identify the statements that accurately describe the drug penicillin. Penicillin interferes with the synthesis of peptidoglycan, weakening the bacterial cell wall. ? Certain bacterial strains, such as S. aureus, have developed resistance to penicillin. Penicillin is effective only against gram-negative bacteria. Penicillin is used less in modern times because it affects some human cells as well as bacteria. Penicillin is effective only against gram-positive bacteria.
