Help! ASAP, this is due tomorrow and I’m struggling as this isn’t what they taught us. The question is: Explain why the bacteria shown (E. coli) have a second membrane outside the
peptidoglycan.

Respuesta :

The second membrane protects e.coli (Gram-negative bacteria) against a harsh environment.

The outer membrane indirectly helps stabilize the inner membrane as peptidoglycan layer in Gram-negative bacteria is relatively thin than gram positive bacteria ( they have multilayer pepdtidoglycan )

Answer:

The outer membrane of Escherichia coli consists of lipopolysaccharide, phospholipid, protein and Enterobacterial common antigen. The outer membrane as a layer has a protective function. Several specific functions can be attributed to individual constituents. hope this helps!
