Cell Structure Ch.4 Flashcards
Ether linkages in phospholipids in monolayer
Archea
Pili protrude from the surface of
Gram-negative bacteria (+ on some gram-positive bacteria such as Corynebacterium diphtheria & Streptococcus species)
The disaccharide in the peptidoglycan of bacteria is made of
N-acetulglucosamine(NAG) and N-acteylmuramic acid(NAM)
Endoflagella are found in
Spirochettes
Bordetella pertussis’ pili adhere to
cells of the mucosal surface of the upper respiratory tract
The disaccharide in the peptidoglycan of archea is made of
N-acetylglucosamine(NAG) and N-acetyltalosamine uronic acid(NAT)
Examples of encapsulated pathogens
Streptococcus pneumonia & Bacillus anthracis
Sterols are present in the cell membrane of
Mycoplasma
Example of bacteria with slime layer
Streptococcus mutans
Very thick,rigid peptidoglycan wall:
Gram-Positive bacteria cell wall
Used for motility and chemotaxis
Flagella
Presence of lipopolysaccharides (LPS) in the outer half of the outer membrane
Gram-Negative bacteria cell wall
Presence of outer membrane and periplasm
Gram-Negative bacteria cell wall
Hexagonal patterns of protein or glycoprotein self-assembled into a crystalline lattice
S-layer
Contains techoic acid
Gram-Positive bacteria cell wall
