In eukaryotic cell architecture, what is a major structural polysaccharide found in fungal cell walls?
A
Lipopolysaccharide (LPS)
B
Peptidoglycan (murein)
C
Chitin
D
Cellulose
Verified step by step guidance1
Understand that the question asks about a major structural polysaccharide specifically found in fungal cell walls, which is a key component providing rigidity and shape.
Recall that lipopolysaccharide (LPS) is a molecule found in the outer membrane of Gram-negative bacteria, not fungi.
Recognize that peptidoglycan (murein) is the main structural polysaccharide in bacterial cell walls, especially in Gram-positive bacteria, but not in fungi.
Know that cellulose is a polysaccharide found primarily in the cell walls of plants, providing structural support, but it is not a major component of fungal cell walls.
Identify chitin as the correct answer because it is a long-chain polymer of N-acetylglucosamine, a derivative of glucose, and is the major structural polysaccharide in fungal cell walls, giving them strength and rigidity.
