Because bacterial cells and human cells aren't the same. Penicillin works by interfering with how bacterial cell walls are built, and human cells don't have bacterial cell walls. (Turns out all bacterial cells aren't the same, either, but penicillin works against a lot of them.) One of the challenges in medicine is finding antibiotics that work against bacteria's Biology, but that don't interfere with human biology. This is called selectivity. It's a really important principle of medications against all infections (you want the drug to selectively kill the infecting organism instead of your own cells) and against cancer, too (you want the drug to selectively kill the cancer cells instead of the healthy ones).

How do antibiotics work to target bacteria without causing harm to the surrounding human cells?
Antibiotics work by targeting specific structures or processes in bacteria that are essential for their survival, such as cell wall formation or protein synthesis. These structures or processes are not present in human cells, so the antibiotics are able to selectively kill the bacteria without harming human cells.
What is an explanation of how antibiotics kill bacteria?
antibiotics kill bacteria by penicillin that works by weakening the cell walls of some bacteria and causing the cells to burst
How does antibiotics kill bacteria without harming human cells?
Antibiotics target specific bacterial structures or functions that are not present in human cells. For example, many antibiotics inhibit bacterial cell wall synthesis, disrupt protein synthesis by binding to bacterial ribosomes, or interfere with bacterial DNA replication. Since human cells lack these unique features, antibiotics can effectively kill bacteria while leaving human cells unharmed. This selective targeting is crucial for their therapeutic effectiveness.
How does antibiotics help bacterial infections?
Antibiotics either directly kill bacteria cells or inhibit bacteria cells from dividing, thus allowing the body to eliminate the infection.
What compound kills bacteria without harming the cells of humans?
Antibiotics such as penicillin and tetracycline are effective in killing bacteria by targeting specific bacterial cell components that are absent in human cells, thus reducing the risk of harm to human cells. However, misuse or overuse of antibiotics can lead to antibiotic resistance in bacteria, diminishing their efficacy over time.
Why do protein synthesis inhibitor a.k.a antibiotics affect bacteria only but not human cells?
most of the antibiotics kill or inactivate bacteria by inhibitting the protein synthesis... protein synthesis consists of 'transcription' and 'translation'.. the translation process requiers mRNA and ribosomes.Human(eukaryotic) ribosome is different from bacterial(prokaryotic) ribosome... Antibiotics inhibit the protein synthesis by altering the ribosomal constitution.Since human ribosomes are different from bacterial ribosome,the substances which are harmful to bacterial ribosome doesn't harm human ribosomes.. Thus human cells are immune to antibiotics..
How do antibiotics control disease?
Antibiotics kill bacteria.
Drug that can kill bacteria?
Bacteria are generally killed by antibiotics which are prepared by either or bacteria or microorganisms and are specifically known as BACTERIOCIDAL
Why the antibiotics are ineffective against viral diseases?
Antibiotics kill bacteria by recognising the antibodies secreted by the bacteria, then attach themselves to the bacteria and give out a signal calling for white blood cells (phagocytes) to eat up the bacteria. Viruses do not secrete the antibodies recognised by antibiotics as they do not resemble proper cells, therefore antibiotics cannot recognise viruses and thus they cannot be digested by phagocytes.
Why is there not a cure for salmonella?
The trick with curing a bacterial infection is to find something that will kill that particular type of bacteria, but which will not kill human cells. Since the biochemistry of human cells is very similar to that of bacteria, most of the things that kill bacteria will also kill human cells. You do not want to cure a disease at the expense of killing the patient. So, there is no guarantee that such cures can be found. You can do research into various antibiotics, but you may or may not find something that works. Furthermore, even when you do find a good antibiotic, bacteria tend to evolve resistant strains which can no longer be killed by that particular antibiotic. Bacteria are very tough, adaptable organisms. Do not underestimate them.
Why cant you use antibiotics to kill virus but bacteria can be killed by antibiotics?
Because bacteria and viruses are two completely different things. Antibiotics - as their name implies - will kill bacteria, but antibiotics simply have no effect on viruses.
Why do antibiotics kill bacteria for?
Cactus!
