bacterial cell structure and function Flashcards
prokaryotes have genetic material in
cytoplasm
prokaryotes also include
photosynthetic bacteria
phospholipid has
hydrophillic head
fill in this
uncharged FA——> ………… ———> …………..
gylcerol portion
charged phosphate group
in arachae there are two membranes
ether link
ester link
is ether link or ester link L
ether link
is ether link or ester link D
ester
which one is branched
ether
cell shape in bacteria tend to be
sphere rod
bacteria cellular morphology tend to be
coccus cocco bacillus vibrio bacillus spirillium spichere
spherical cells have cocci shape they can be
diplocci
strep
staph
rod cells can be
bacilli bacillus or stick
function of capsules/mucilage
adherancce
protect
bacterial cell wall made of
peptidoglycan
and repeating
N-acetylglucosame
N-acetylmuramic acid
what is the cell wall also made of
L and D isomer of AA
2 group of bacteria
gram positive and gram negative
gram reaction steps
fix crystal violet iodine Treat Decolour Counter Stain with safarin
Gram positive bacteria properties:
thick cell wall high internal osmotic pressure high peptidoglycan content wall has other polymers typically sensitive to lysozyme
Gram negative bactera properties:
thin cell wall
low internal osmotic pressure
low peptidoglycan content
3 main parts
basal body
hook
spiral microfill
F pillus
hollow protein microtubule
25nm diameter
central pole
cytoplasm has cytoskel
internal protein microtubule
function of ribosomes
protein synthesis
ribosomes are made of 2 sub-units
true
spores are formed inside
patent cells
