Lesson 2.2 Archaeal Cell Wall Flashcards
Bacteria have peptidoglycan while archeans have ______
pseudomurein
Not all aracheans have pseudomurein, but species like ____
methanogens
How do archeans cell wall composition differ from bacteria?
Both have N-acetylglucosamine but archaeans have N-acetyltalosaminuronic acid
How do archeans cell wall differ from bacteria?
Glycosidic bond
Archaeal cell wall: connected to beta-1,3 instead of 1,4
Difference between peptidoglycan and psuedomurein
Peptidoglycan: sensitive to lysosomes
Psuedomurein: unbreakable
Most common type of cell wall in Archaea
S layer or paracrystalline surface layer
It is consists of interlocking molecules of protein or glycoprotein
S layer
S layer is consists of varied symmetries such as
hexagonal and pentagonal
S layers can be found in all representative of Arachea
true
S layers can also be found in bacteria
true
S layer is relatively weak to withstand osmotic pressure withou other wall components
false
