In cell biology, what is the primary structural polysaccharide that makes up most fungal cell walls?
A
Chitin (a polymer of N-acetylglucosamine)
B
Cellulose (a polymer of glucose)
C
Lipopolysaccharide (LPS)
D
Peptidoglycan (murein)
Verified step by step guidance1
Understand that the question asks for the primary structural polysaccharide in fungal cell walls, which is a key component providing rigidity and shape.
Recall that fungal cell walls are distinct from plant and bacterial cell walls in their composition.
Identify that cellulose is primarily found in plant cell walls, not fungal walls.
Recognize that peptidoglycan is a major component of bacterial cell walls, and lipopolysaccharide (LPS) is part of the outer membrane of Gram-negative bacteria, so neither applies to fungi.
Conclude that chitin, a polymer of N-acetylglucosamine, is the main structural polysaccharide in fungal cell walls, providing strength and protection.
