Question: Which bacterial cell structure confers its shape and rigidity: A. Cell capsule made of glycoproteins B. Sacculus made of plasma membrane C. Sacculus made of peptidoglycan D. Nucleoid E. Cell capsule made of polysaccharides
Anitha M.
The bacterial capsule is comprised of tightly packed repeating polysaccharide units. It is the outermost layer that is linked to the cell surface covalently, either to phospholipid or lipid-A molecules. The capsule is a virulence factor that increases disease occurrence by protecting bacteria against phagocytosis. It may also facilitate colonization and adherence of bacteria to surfaces. All choices. Both A and C.
