Final answer:

Daptomycin and polymyxin target bacterial cell membranes.


Step-by-step explanation:

The two drugs that target bacterial cell membranes are daptomycin and polymyxin. Daptomycin is a lipopeptide antibiotic that inserts into the bacterial cell membrane, leading to depolarization and disruption of the membrane, ultimately causing cell death. Polymyxin is a cationic cyclic peptide antibiotic that binds to the lipopolysaccharides in the outer membrane of Gram-negative bacteria, disrupting the integrity of the membrane and causing leakage of intracellular contents.
