Many antibiotics work by blocking the function of ribosomes, which are essential for protein synthesis in bacteria. By inhibiting ribosomal activity, these antibiotics prevent bacteria from producing the proteins necessary for their growth and reproduction. This ultimately leads to the death of the bacteria or halts their proliferation, making antibiotics effective in treating bacterial infections. However, this mechanism can also affect human cells, albeit to a lesser extent, which is why antibiotic use must be carefully managed.
They become immune by mutating and blocking certain receptors on the bacteria's surface, which would normally be where the antibiotics would attach to.
Antibiotics kill bacteria through various mechanisms: Inhibition of Cell Wall Synthesis: Antibiotics like penicillin interfere with the formation of the bacterial cell wall, leading to cell lysis. Disruption of Protein Synthesis: Drugs such as tetracyclines bind to bacterial ribosomes, preventing them from producing essential proteins. Inhibition of Nucleic Acid Synthesis: Certain antibiotics, like fluoroquinolones, disrupt DNA replication and repair processes. Disruption of Metabolic Pathways: Sulfonamides mimic substrates in bacterial metabolic pathways, blocking essential enzyme functions. Alteration of Cell Membrane Integrity: Some antibiotics, such as polymyxins, disrupt the bacterial cell membrane, leading to leakage of vital cell contents.
Protein synthesis can be stopped by blocking translation, primarily by inhibiting the functions of ribosomes or tRNA molecules in the cell. For example, antibiotics like puromycin can prematurely terminate protein synthesis by mimicking the structure of aminoacyl-tRNA and binding to the A site on the ribosome. Additionally, certain drugs or compounds can target key components of the translation machinery to halt protein synthesis.
HIV is a virus. Antibiotics have no effect on viruses since they are not really "alive" in the strictest sense. "Antibiotic" literally means anti-life. Antibiotics work by blocking a fundamental life process in bacteria, effectively poisoning them. Since viruses (HIV included) work by subverting the cells they invade into making copies of themselves, antibiotics are not effective.
the both get in the way of the real nutrients therefore blocking the nutrients from getting into the plant.
the antibiotic binds to bacterial ribosomes when the antibiotic is taking to kill the bacteria, as the antibiotics is taking it bind to the smaller subunit of the bacterial ribosomes ,preventing the bacterium making new protein.
Antibiotics can target various aspects of prokaryotic transcription. First, rifamycins inhibit RNA polymerase by binding to the β-subunit, preventing the initiation of RNA synthesis. Second, actinomycin D intercalates into DNA, blocking the movement of RNA polymerase along the DNA template. Lastly, some antibiotics, like streptolydigin, also interfere with RNA polymerase function, disrupting transcription progress.
not blocking means where you do not stand in font of someone (not blocking them)
Only microbes have ionophones, which are channels in their membranes. By blocking them using antibiotics, the cell will die as they can not bring ions in and out of their cells. Human cells don't have these and so are not affected by those antibiotics.

Antibiotics are only for killing bacteria, they do not work on viruses which are the cause of the flu. Bacteria are living organisms and so poisons and chemicals can actually kill them. But flu viruses are non-living organisms so they can not be killed, they can only be inactivated by damage or physical blocking by antibodies (made by our immune systems) of the shapes of the structures viruses use to attach to a host's cells. Viruses need a host's cells to use to reproduce, if they can not attach to the cells, they will be inactivated. Antibiotics are not capable of inactivating them.
