What are antibiotics?
- Proteins/sugars in the bacterial wall
- Important enzymes that make new bacterial DNA or proteins
How were antibiotics discovered?
How do antibiotics work?
- Deactivating a bacterial enzyme (transpeptidase) that builds and repairs the bacteria wall.
- Activating a bacterial enzyme (autolysin) that cuts open parts of the bacterial wall, an enzyme normally only activated when the bacteria is multiplying.
- Blocking the cell's ability to create proteins by attaching to ribosomes in the cell.
