Question 50
Which is absent in the cell wall of bacteria?
A. Protein
B. Polysaccharide
C. Chitin
D. Lipid
Solution
The answer is C. Chitin.
Here's the step by step explanation:
A) Protein: Bacterial cell walls do contain proteins. These proteins can serve various functions, including transport, structure, and enzymatic activity.
B) Polysaccharide: The main component of bacterial cell walls is a polysaccharide called peptidoglycan. This is a complex molecule made of sugars and amino acids.
C) Chitin: Chitin is a polysaccharide found in the cell walls of fungi and the exoskeletons of insects and crustaceans. It is not found in the cell walls of bacteria.
D) Lipid: Lipids are also present in the cell walls of bacteria. They are part of the lipopolysaccharide layer in Gram-negative bacteria, which helps protect the bacteria from the environment and contributes to its pathogenicity.
