How does tetracycline enter gram positive and gram negative bacteria?
Diffuses and is pumpedinto both gram negative and gram positive bacteria
How does tetracycline stop protein synthesis?
It binds to the small subunit of ribosomes and blocks tRNA attachment in the second position, so no new amino acids can be added to a polypeptide chain (blocks tRNA binding site)
Why is tetracyclinebacteriostatic?
When there is no tetracycline, tRNA binding sites are no longer blocked, so protein synthesis can occur. It only pauses cell reproduction
