Antibiotics work by poisoning pathogenic bacteria more than host cells. Some antibiotics, such as penicillin, achieve specificity by poisoning bacterial components not present in animal cells. Which of the following is a component present in most bacterial cells but not animal cells? Correct Answer(s) cell membrane DNA energy-generating respiratory proteins cell wall Incorrect Answer(s)

An ideal antibiotic damages only bacterial cells but not human cells. Which of the following cellular structures would be a good target for antibiotics?
Adi S.
When a human or any other organism is infected with a bacterial infection, antibiotics can be used to treat it. Antibiotics work by targeting prokaryotic cells without harming eukaryotic ones. This is possible because there are molecular differences between the two cell types that allow for specific targeting of molecules in prokaryotic cells. For example, antibiotics can disable DNA topoisomerase, which would affect the functioning of prokaryotic cells. Similarly, some antibiotics can inhibit peptidoglycan synthesis, which would also affect prokaryotic cells.
If you want an antibiotic to specifically kill the bacterial cells without affecting the human cells, the antibiotic should target the ___. (MARK ALL THAT APPLY) cholesterol in the cell membrane 80S ribosomes peptidoglycan cell wall 70S ribosomes DNA
