Study Notes
Bacterial Cell Wall Functions
- Prokaryotic cell walls perform several functions, including maintaining cell shape, offering physical protection, preventing cell lysis in hypotonic environments, providing resistance to antibiotics, and enabling bacteriophage attachment.
Peptidoglycan Structure
- Most bacterial cell walls contain peptidoglycan, a polymer of modified sugars cross-linked by short polypeptides.
Archaea Cell Walls
- Archaea cell walls lack peptidoglycan.
