What Cellular Structure Do Antibiotics Typically Target? Antibiotics are drugs that kill or inhibit the growth of bacteria. They work by targeting specific cellular structures within bacteria. The most common cellular structures targeted by antibiotics are ribosomes, the cell wall, the cell membrane, and DNA.
Ribosomes are responsible for protein synthesis. Antibiotics that target ribosomes can inhibit protein synthesis, which can lead to the death of the bacteria. Examples of antibiotics that target ribosomes include tetracycline, erythromycin, and chloramphenicol.
Ribosomes
Ribosomes are complex structures composed of ribosomal RNA (rRNA) and proteins. They are the sites of protein synthesis in the cell, where they decode the genetic information in messenger RNA (mRNA) and assemble amino acids into polypeptide chains. Ribosomes are composed of two subunits, a large subunit and a small subunit, which come together to form a functional ribosome.Ribosomes
are targets for a variety of antibiotics, which can inhibit their function and prevent protein synthesis. Some antibiotics, such as tetracycline and erythromycin, bind to the small subunit of the ribosome and block the binding of mRNA. Others, such as chloramphenicol and puromycin, bind to the large subunit of the ribosome and inhibit the formation of peptide bonds.
Examples of antibiotics that target ribosomes:
- Tetracycline
- Erythromycin
- Chloramphenicol
- Puromycin
Wrap-Up: What Cellular Structure Do Antibiotics Typically Target
In conclusion, antibiotics target a variety of cellular structures within bacteria. By targeting these structures, antibiotics can inhibit bacterial growth and reproduction, leading to the death of the bacteria.
