This is essentially because bacterial cells and human cells are very different. Both bacterial and human cells use chemicals called enzymes to build their walls. Penicillin is the right chemical "shape" to chemically stick to part of the bacterial enzyme. When it does this, it stops the bacterial enzyme from working properly and this makes the bacterial cell walls weak. The weakened cell wall cannot withstand the outside pressure, it breaks up and the bacterial cell dies. Human cells are made by different types of enzymes with a different chemical shape that penecillin is unable to stick to so it cant stop the human enzymes from working. The human cell walls are thus unaffected by it and they remain strong.

Does erythromycin affect human cells?
No
Why pencilin does not harm human cells?
Penicillin attacks the peptidoglygan cross linking of bacterial cell walls and these bacteria are prokaryote. Human cells do not have cell walls and are eukaryote in domain.
How do lysozyme and penicillin differ in their effect on cell walls?
Penicillin blocks the final stages of peptidoglycan synthesis. If penicillin is present when bacterial cells are dividing, the cell cannot form complete wall and they die.The enzyme lysosome, found in human body secretions, digest peptidoglycan . This helps prevent bacteria from entering the body.
Why does penicillin kill only actively multipling cells and lysozyme will kill cells in any stage of growth?
Penicillin inhibits transpeptidase, and enzyme that is necessary for bacterial cell wall synthesis. If a cell is not actively multiplying, then no cell wall synthesis is occurring and, therefore, penicillin does not inhibit the bacteria.
Can stem cell affect human life?
That question seems a little vague to me. However, what I can say is that stem cells are used to aid human life. They are essentially cells that have not yet developed for a specific function in the body. Because of this, they can (put very simply) be maniplated to grow into a cell with a needed function in a human. This can aid in repairing spinal injuries, and possibly eventually cure para or quadriplegic patients. It is also involved prototypically in the development of insulin-producing pancreatic cells--aiding people with diabetes in a possibly permanent manner. So, essentially, yes--stem cells can absolutely affect human life.
Does erythromycin affect human cells?
No
Does penicillin affect birth control?
Penicillin does not affect birth control.

What cells produce penicillin?
Penicillin is a drug. But som cells produce pencillinas which can, so to speak, neutralize the penicillin. If you don't know what penicillin is you really should go back to elementary school.
How does the environment affect human cells?
Yes, it can cause cancer.
Why doesn't penicillin kill humans?
The penicillin kills bacteria by interfering with repairs to the bacterial cell wall. Human cells don't have a cell wall, and don't use the same enzymes that make the bacteria vulnerable.
Why do antibiotics kill bacteria and not human cells?
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).
Can horses have human penicillin?
Procaine Penicillin, Amoxicillin etc. Can be used on horses.
Explain the effect of penicillin on prokaryotic and eukaryotic cells?
penicillin destroys the cell wall on prokaryotic cells no effects on animal cells since they don't have a cell wall but might have an effect on plant cells
Does metronidazole affect the birth control pill?
does metronidazole affect the contraceptive injection? im on penicillin the same time aswell but my health clinic said penicillin doesnt affect the injection? is this right? :/

Who discovered the effect of penicillin on living cells?
Alfred nobel
