Which of the following features is NOT characteristic of the members of the kingdom Fungi?
Heterotrophic mode of nutrition
Presence of chlorophyll a and b
Cell wall made of chitin
Reproduction by spores
Which specific characteristic of fungal cell walls makes them resistant to degradation by common bacterial enzymes like lysozyme?
Presence of cellulose
Presence of chitin
Presence of peptidoglycan
Presence of lignin
Which of the following is NOT a characteristic feature of Fungi?
Heterotrophic nutrition
Cell wall made of chitin
Reproduction by spores
Autotrophic nutrition
Chitin, a structural polysaccharide found in the exoskeleton of insects and crustaceans, is composed of which monomers linked by what type of glycosidic bond?
Glucose; ฮฑ-1,4-glycosidic bond
N-acetylglucosamine; ฮฒ-1,4-glycosidic bond
Fructose; ฮฒ-2,1-glycosidic bond
Galactose; ฮฑ-1,4-glycosidic bond
Chitin, a structural polysaccharide found in the exoskeleton of arthropods, differs significantly from cellulose in terms of its monomeric unit. This difference primarily stems from:
The presence of an N-acetyl group at C-2 of the monomer
The type of glycosidic linkage between monomers
The degree of polymerization (chain length)
The three-dimensional arrangement of the polymer chains
Chitin, a major component of fungal cell walls and arthropod exoskeletons, is a polymer of:
Glucose
Galactose
N-acetylglucosamine
Fructose
Chitin is a polysaccharide found in:
Plant cell walls
Animal liver
Bacterial cell walls
Exoskeleton of insects
Chitin, the primary component of fungal cell walls, is a:
Simple sugar.
Lipid.
Protein.
Complex polysaccharide.
The cell wall of most fungi is primarily composed of:
Cellulose
Chitin
Peptidoglycan
Lignin
