🩵Chapter 3: Bacteria Cell Wall Anatomy Flashcards
Cell Wall Functions
a. Provides cell shape and integrity
b. Protects cell against physical damage
c. Allows bacteria to stick to other cells
d. Protects bacteria from being identified by immune system
Types of Cell Wall
Gram (+) and Gram (-)
Gram (+)
mostly made of a thick layer of peptidoglycan
Peptidoglycan
partially made up of protein and sugar
What’s another part of the gram (+) cell wall?
Teichoic Acid
Teichoic Acid
attaches/sticks to molecules on the surface of other cells
Gram (-)
made of a thin layer of peptidoglycan and outer membrane
Outer Membrane
2nd plasma membrane
What’s another part of the gram (-) cell wall?
Lipopolysaccharide (LPS)
Lipopolysaccharide (LPS)
sticking to cells
What is Lipopolysaccharide?
part fat, mostly sugar
