Cell Structure

Question 1

Space between cell outer membrane and peptidoglycan in GN (sometime in GP btwn pepti and inner membrane)

Answer 1

Periplasmic space (contains periplasm)

Smaller in GP because of porous cell wall

Question 2

Another word for peptidoglycan

Answer 2

Murien

Question 3

Peptidoglycan contains these two subunits that linked in meshlike polymer with amino acids

Answer 3

NAG (N-acetyl-glucosamine) and NAM (N-acetylmuramic acid)

Amino acid are alternating D/L attached to NAM - the D orientation is not found in proteins and protects from peptidases

Is helical strong but porous structure

Question 4

In both GP and GN - adjacent to plasma membrane

Answer 4

Peptidoglycan layer

Question 5

Teichoic acid

Answer 5

Found GP peptido layer

Give GP cell wall a negative charge

Question 6

S-layer

Answer 6

Superman layer

Protein found on exterior of peptido (GP) and outer membrane (GN) for extra protection

Question 7

Acid fast GP

Answer 7

Extra mycolic acid layer (mycobacterium tuberculosis)
