Penicilin works best on Gram-positive bacteria. However, Gram-negative bacteria also have cell walls. Why isn't penicillin used for the treatment of infections caused by Gram-positive bacteria? Select one: Gram-negative cells contain porin proteins that pump penicillin out of the cell, preventing its function as an antibiotic. Gram-positive bacteria have a thicker layer of peptidoglycan, which allows transpeptidase activity to be highest there. Gram-negative bacteria have a thinner layer of peptidoglycan so there is less transpeptidase activity to block. Gram-negative bacteria contain efflux pumps that pump penicillin out of the cell, preventing it from functioning as an antibiotic. Gram-negative bacteria contain a thick layer of mycolic acid, preventing the antibiotic from even reaching the cell wall.
