is a huge polymer of interlocking chains of alternating sugar monomers held together with peptide bridges.

Peptidoglycan

52- Flashcard

Provides rigid support while freely permeable to solutes.

Bacterial cell wall

53- Flashcard

Two main types of bacteria cell wall:

·       Gram-positive

·       Gram-negative

54- Flashcard

- Peptidoglycan makes up as much as 90% of the thick, compact cell wall.

Gram-positive

- More chemically complex and thinner.

Gram-negative

56- Flashcard

Peptidoglycan only(blank) of the cell wall.

5 – 20%

57- Flashcard

Peptidoglycan not outermost layer, between the plasma membrane and the outer membrane.

Bacterial cell wall

58- Flashcard

Outer membrane is similar to the plasma membrane but is less permeable and composed of lipopolysaccharides (LPS).

Bacterial cell wall

60- Flashcard

The space between the cell wall and the plasma membrane is called

periplasm.
