cell walls and envelopes

Cell wall

What makes up the outer most layer of gram positive bacteria

Envelope

What makes up the out most layer of gram negative bacteria

Cell wall

What surrounds bacterial cytoplasmic membrane

Maintain bacterial cell’s size and shape, provide strength, and helps resist changes in osmolarity of the external environment

What is the function of the cell wall

The inner side of the cytoplasmic membrane

Where the ETC located

Tail on some bacteria used for motility

What is flagella

Extensions on the surface of some cells used for adhesion

What is a pili/fimbria

Gram positive

What type of bacteria has a thicker peptidoglycan cell layer

Gram negative

What bacteria has a thinner peptidoglycan cell wall

Thin peptidoglycan layer between outer membrane(LPS) and cytoplasmic membrane

How is the gran negative cell wall oriented

Glucans, tetrapeptide side chain, and peptide cross link

What does a cell wall consist of

The cell wall

What is the major target of manny antibacterial agents

Teichoic acid (modulate immune response)

What are found in gram positive cell walls

Gram negative or positive

What types of bacteria can have a capsule

Allows direct growth in the blood stream, protects against immune response.

What is the function of a capsule

The outer membrane consists of LPS

What is unique about the gram negative bacterial envelope

Cause immune response and toxic shock

What is the function of LPS

O antigen and Lipid A

What are the components of LPS

Space between the outer membrane and cytoplasmic memebrane. Where thin cell wall is located on gram negative bacteria

What is periplasm

Flagella (H), LPS (O), and capsule (K)

What are the main serotypes of bacteria

YES

Can you stain for a capsule

Use chemoattractant

How do bacteria determine direction if motile

Mycobacteria

What bacteria lacks a cell wall
