Gram positive cell wall weak to penicillin
WebDue to the structural difference in the composition of the cell walls of Gram-positive and Gram-negative AgNPs have significantly less effect on the growth of Gram-positive bacteria. The Gram-negative bacteria have a layer of lipopolysaccharides on the outside, and present below a thin (7 to 8 nanometers) layer of peptidoglycan. WebMammalian cells are eukaryotic which fail to feature a cell wall, whereas bacteria cells are prokaryotic, containing a cellulose cell wall. As mentioned above, penicillin inhibits the enzymes involved with creating the cell wall, leaving the cell weak and subject to leakage of its contents, causing the cell to be destroyed.
