Why does penicillin not affect human cells?
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.
