Do antibiotics target certain areas?

Indeed, modern antibiotics act either on processes that are unique to bacteria–such as the synthesis of cell walls or folic acid–or on bacterium-specific targets within processes that are common to both bacterium and human cells, including protein or DNA replication.

Why is the cell wall a good target for antibiotics?

Many antibiotics, including penicillin, work by attacking the cell wall of bacteria. Specifically, the drugs prevent the bacteria from synthesizing a molecule in the cell wall called peptidoglycan, which provides the wall with the strength it needs to survive in the human body.
