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

Antibiotics are specially produced to attack the bacterial cells but not the healthy cells of the human body. The modern antibiotics target the bacteria causing infection in the body.These antibiotics are specific to bacteria as the proteins produced by the bacterial cell is different from the proteins produced by the human cell.

Most of the bacterial cell produces the cell wall that is made up of the macro molecule known as peptidoglycan. Human cells does not synthesis peptidoglycan.

In this way the antibiotics target specific kind of protein synthesized by bacterial cell only.
