Question

Explain how antibiotics are able to target the bacteria cells but not the healthy cells within your body.

Answer 1

they have primitive brains

Answer 2

this is what some nutter wrote
This is an explanation of the β-lactam antibiotics (aka penicillins)
These bacteria have a β-lactam ring. It prevents the cross linking of NAM and NAG in peptidoglycan. Peptidoglycan is a major part of the cell wall of gram-positive bacteria. So when NAM (N-acetylglucosamine) and NAG (N-acetylmuramic acid) cannot be cross-linked, the cell wall cannot be completed.

The reason it does not affect human cells is because animal cells do not have a peptidoglycan layer.

Answer 3

thats they answer?

Answer 8

WARNING WARNING! Gram positive is susceptible to antibiotics like penicillin. Gram positive bacterium will died when the antibiotic is used.

However, in a gram negative bacterium, they have an EXTRA phospholipid bilayer which contains the ANTIBIOTIC resistance called lipopolysaccarides (Gram positive do not have this).

E. coli is a gram-negative bacterium (bacilla shaped: rod) and its resistance to some antibiotics because it has that extra phospholipid bilayer.

Answer 9

Oh, antibiotics doesnt target human cells because we dont have a cell wall (peptidoglycan).
