Question
Which of the following statements accurately describes specific bacterial cell walls?In bacteria with acid-fast cell walls, the carboxylic acid in the walls forms a layer outside of a thin layer of hydrophilic polypeptides.
Gram-negative bacterial cell walls contain teichoic acids, whereas, the cell walls of gram-positive bacteria do not.
The cell walls of gram-negative bacteria contain many more layers of peptidoglycan than those of gram-positive bacteria.
In gram-negative bacteria, the thin layer of peptidoglycan is bonded to lipoproteins.
Explanation / Answer
Answer: In gram-negative bacteria, the thin layer of peptidoglycan is bonded to lipoproteins. Gram-positive has thick layers of peptidoglycan while gram-negative has a thin layer.
