the area between the inner and outer membranes of gram-negative bacteria

the area outside the cell membrane that is influenced by the polymers

the area between the inner and outer membranes of Gram-positive bacteria

It is present in prokaryotic cell wall

None of these

It occurs in the form of a bag shaped macro molecule surrounding the cytoplasm membrane

It is a polymer consisting of N-acetyl glucosamine, N-acetyl muramic acid and amino acids (alanine, lysine, etc.)
