This method of moving molecules across the membrane uses proteins embedded in the membrane, and uses ATP energy to move molecules against (up) the concentration gradient.

Pili

D-Glutamic acid, D-Alanine

Name 2 unique amino acids found in the peptidoglycan of bacterial cell walls.

Capsule

A firmly attached glycocalyx

Purple

Gram positive cells appear _____ after the gram stain procedure.

NAG and NAM

The two monosaccharides which form the sugar backbone of the cell wall peptidoglycan.

Strep

The prefix that identifies long chains of cells.

Fimbriae

The type of bacterial appendage (fine, hairlike) used for attachment, not motility.

Bacillus, Clostridium, Sporosarcina

Name the 3 genera which form endospores.

Hook

The portion of the flagellum that links the filament to the basal body.

The solution surrounding the cell is considered hypertonic .

A cell with an internal salt concentration of 0.1% salt is placed in a solution of 2% salt solution. Is the solution surrounding the cell considered hypotonic or hypertonic?

Thin

Do gram negative cells have thick or thin peptidoglycan layers?

Down

Does diffusion move molecules down or up the concentration gradient

4 rings

How many rings are contained in the basal body of gram negative bacteria?

The insertion of the proteins.

Is it the proteins or the fatty acid tails which are responsible for giving the "Fluid Mosaic Model" of the plasma membrane its MOSAIC portion of the name?

Amphitrichous

The term for bacteria that have a single flagellum at each end.

Passive Transport

This method of moving molecules across the membrane uses proteins embedded in the membrane, but does not use ATP energy. It also moves molecules down the concentration gradient.

Osmosis

This is the diffusion of water.

salt

In a solution consisting of salt dissolved in water, which is the solute?

The major bacterial genus that has bacteria with axial filaments

Hypotonic

When the solute concentration is less.

Selective Permeability

The term for membranes which allow some molecules to pass through while blocking passage of other molecules.

Teichoic Acids

What molecules are found in gram positive cell walls and NOT in gram negative?

Polypeptides

Adjacent rows of NAG and NAM are crosslinked by these.

Antigen

O Polysaccharide of the LPS layer of gram (-) cells acts as _______.

Group Translocation

When a substance is chemically altered as it is moved across the plasma membrane

Axial Filaments

The type of filaments which wrap around the bacterial cell and give it a corkscrew type movement.

Hypertonic

When the solute concentration is greater.

Out of the cell.
