Which of the following is a component of the prokaryotic cell wall that contributes to bacterial invasiveness?

• A. Chitin
• B. Cellulose
• C. Peptidoglycan
• D. Lignin

Answer: (C)

Verified step by step guidance

1. Understand the structure of prokaryotic cells: Prokaryotic cells, such as bacteria, have a cell wall that provides structural support and protection.
2. Identify the components of the prokaryotic cell wall: The cell wall of bacteria is primarily composed of peptidoglycan, a polymer consisting of sugars and amino acids.
3. Recognize the role of peptidoglycan: Peptidoglycan contributes to the rigidity of the bacterial cell wall and is involved in maintaining the shape of the cell.
4. Consider the function of peptidoglycan in bacterial invasiveness: Peptidoglycan can play a role in the ability of bacteria to invade host tissues by providing structural integrity and protection against environmental stresses.
5. Differentiate peptidoglycan from other substances: Chitin, cellulose, and lignin are not components of the bacterial cell wall. Chitin is found in fungal cell walls, cellulose in plant cell walls, and lignin in the secondary cell walls of plants.
