Question

1. Match the prokaryotic cell structure with its function(s) or its role(s) in disease by placing the letter(s) on the blank line. Note: Each structure may have more than one function/role associated with it. However, each function/role will be used only one time. (1/4 pt. each correct answer; -1/4 pt. each incorrect answer)

Prokaryotic Cell Structure	Function or Role in Disease
Peptidoglycan	Site of protein synthesis (a.k.a., translation)
Flagellum (flagella);              Axial fibrils (a.k.a, endoflagella,                                              periplasmic flagella)	Reception and processing of electrochemical communication signals; Quorum sensing
Glycocalyces: Capsule; Slime layer	Protection from drying, antibiotics. etc.
Fimbriae	Non-specific adherence
Lipid A of Lipopolysaccharide (LPS)	Specific adherence
Ribosomes	Polysaccharide barrier protects bacteria against phagocytosis
Plasmid	Motility
	Biofilm formation
	May carry genes for antibiotic resistance, virulence factors, metabolic factors, etc.
	Serves as endotoxin and can affect all human body systems
	Provides rigidity and shape to cell
	One component can be used to classify living organisms
	Provides protection from osmotic fluctuations

Answer 1

Ans.)

Prokaryotic Cell Structure Function or Role in Disease

• Peptidoglycan Provides rigidity and shape to cell
• Flagellum   Motility
• Capsule Protection from drying, antibiotics. etc., Polysaccharide barrier protects bacteria against phagocytosis, Provides protection from osmotic fluctuations
• Fimbriae   Specific adherence, Non-specific adherence
• Lipopolysaccharide Serves as endotoxin and can affect all human body systems
• Ribosomes   One component can be used to classify living organisms
• Plasmid May carry genes for antibiotic resistance, virulence factors, metabolic factors, etc. , Reception and processing of electrochemical communication signals; Quorum sensing, Biofilm formation
•
