Question

which term is used to describe the phospholipid barrier surrounding the peptidoglycan layer in gram - negative bacteria?
o nuclear membrane
o plasma membrane
o outer membrane
o cytoplasmic membrane

Explanation:

Gram - negative bacteria have a unique cell - wall structure. The outer membrane is a phospholipid barrier that surrounds the peptidoglycan layer. The nuclear membrane is not present in bacteria as they are prokaryotes. The plasma membrane (also called cytoplasmic membrane) is inside the peptidoglycan layer in gram - negative bacteria.

Answer:

C. outer membrane
