Antibiotics Interference with Protein Synthesis Flashcards
1
Q
What are antibiotics produced to do?
A
- counteract bacterial infections
2
Q
How do antibiotics counteract bacterial infections?
A
- by interacting with the bacterial ribosomes
- and inhibiting their function of protein synthesis
3
Q
Why can antibiotics specifically target the ribosomes of bacteria and not those of the host?
A
- because the ribosomes of bacteria (prokaryotes) and eukaryotes are different enough
4
Q
Why do antibiotics help to inhibit the spread of infection?
A
- proteins are essential for the production and growth of new cells
- so if bacteria are prohibited from making proteins
=> they will not be able to make new cells to spread the infection
5
Q
What does the tetracycline variety of antibiotics do?
A
- prevents the attachment of tRNAs carrying amino acids
6
Q
What does the chloramphenicol variety of antibiotics do?
A
- prevents the formation of peptide bonds
7
Q
How can antibiotics be changed if resistance develops?
A
- by targeting different stages of the mRNA translation
