ntibiotics are medicines used to fight bacterial infections. These drugs kill prokaryotic cells without harming human cells. What part or parts of the bacterial cell do you think the antibiotics target? Why?
When we have a bacterial infection, we often take antibiotics. Why do antibiotics only kill bacterial cells and not our own human cells?
They do kill human cells but there are far more human cells than bacterial cells and they will quickly repopulate after the infection.
Antibiotics are proteins that can only bind to bacterial cell wall receptors.
Antibiotics target structures of bacterial cells that human don't have, such as a nucleus.
Antibiotics target structures of bacterial cells that human don't have, such as peptidoglycan.

what are three cellular parts that are specific to ALL bacteria? This should not include any cellular parts listed that both prokaryotes and eukaryotes will have. This also should not include cellular parts that only specific types of bacteria will have (example: flagella). Then state the function of the cellular part (what does it do for the cell?
