What characterizes the cell wall composition of Gram negative bacteria?
Understand the Problem
The question is asking about the specific characteristics of the cell wall composition of Gram negative bacteria, particularly focusing on the presence and structure of peptidoglycan and whether it is thick or thin.
Answer
Thin peptidoglycan layer and outer membrane with lipopolysaccharides.
Gram-negative bacteria have a cell wall composed of a thin layer of peptidoglycan, surrounded by an outer membrane containing lipopolysaccharides.
Answer for screen readers
Gram-negative bacteria have a cell wall composed of a thin layer of peptidoglycan, surrounded by an outer membrane containing lipopolysaccharides.
More Information
A key characteristic of Gram-negative bacteria is their outer membrane, which makes them more resistant to certain antibiotics compared to Gram-positive bacteria.
Tips
A common mistake is confusing the thinner cell wall of Gram-negative bacteria with Gram-positive, which have thicker peptidoglycan layers.
