LESSON 3d: CELL WALL Flashcards
A complex semi-rigid structure that holds the shape, prevent rupture of bacterial cell, and attachment of flagella.
Cell wall or bacterial cell wall
Composition of bacterial cell wall:
peptidoglycan or murein:
NAG and NAM:
N-acetylglucosamine, and N-acetylmuramic acid
A bacteria that has a thick cell wall and teichoic acid.
Gram positive cell wall
This attached the cell wall to membrane
Lipoteichoic acid
A bacteria that has a thin cell wall, and has periplasm layer between cell wall and cytoplasmic membrane.
Gram negative cell wall
In a gram negative bacteria, ________________ can be found between cell wall and cytoplasmic membrane.
Periplasm layer
This type of bacterial cell wall has high resistant against antibiotics and dye.
Gram negative cell wall
What does anti-biotics do to the cell wall of bacteria?
Prevents biosynthesis of the peptidoglycan.
This is composed of alternating repetitions of N-acetylglucosamine, and N-acetlymuramic acid.
Peptidoglycan
What type of bacterial cell wall that exhibits a short peptide interbridge?
Gram positive bacteria
Exhibits no interbridge between NAG-NAM alternating repetition.
Gram negative bacteria
This prevents the bacteria from being eaten (phagocytosis) due to the __________________ charged cell wall.
Negatively Charge
Composed of lipid A and LPS in cell wall.
Gram negative cell wall
What component of cell wall of pathogenic bacteria is toxic?
Lipid A act as an endotoxin for pathogenic bacteria.
What are the types of acid fast bacteria?
Mycobacteria and Nocardia.
