The bacterial cell wall has all of the following properties except______________?
Correct answer: C. It is a unique flexible plastic structure
- A. It consists of a mixed polymer called peptidoglycon
- B. It is the structure principally responsible for the reaction of gram staining
- C. It is a unique flexible plastic structure
- D. It contains D-isomers of amino acids
Explanation
The bacterial cell wall is a rigid peptidoglycan structure, not a flexible plastic structure. Peptidoglycan determines much of the Gram-staining reaction and contains D-amino acids, which protect it from many bacterial proteases.
