Nutrients Media Cell Wall 1 Cell Wall 2 Nothing

This macronutrient is important because it makes up both amino

acids and nucleotides.

What is nitrogen?

This macronutrient is important because it forms the high energy

bonds in ATP.

What is phosphorous?

Siderophores help transfer this macronutrient across the cell

membrane

What is iron?

Micronutrients are important because they are components of these types of

molecules.

What are enzymes?

Vitamins are considered these types

of molecules

What are growth factors or coenzymes?

You would MOST likely use this type of media if you wanted to determine if

your culture was contaminated.

What is solid media or petri dishes with agar?

In this type of media, you know the exact molar composition of the

components that you are adding.

What is chemically defined media?

If you were using a yeast extract, you would be making up this type of

media.

What is chemically complex?

This type of media will inhibit the growth of some organisms

but not others.

What is selective?

In this type of media, addition of specific factors (nutrients) allows

certain organisms to grow that would not normally grow.

What is enrichment?

These are some functions of the cell wall.

What is support/cell shape?

What is protects the interior of the cell from

adverse changes?

What is prevents cells from rupturing?

What is point of anchorage for flagella?

Antibiotics are use to disrupt the bacterial cell wall but are not effective against eukaryotic cells

for this reason

What is most eukaryotic cells do not have cell

walls? If they do, they do not consist of

peptidoglycan which is a major target of antibiotics.

This is the backbone of the peptidoglycan and

these subunits are linked together in this way.

What is NAM-NAG in b1,4 glycosidic linkage?

The four peptides that are involved in linking different chains of

peptidoglycan together are bound to the

peptidoglycan backbone in this location.

What is to NAM?

Peptide interbridges are found in this class of

bacteria.

What are gram positive?

These are some similarities between the gram + and gram – cell

walls.

What is both contain peptidoglycan and both are negatively charged?(teichoic acid in gram +

and LPS in gram -)

These are some differences between the gram + and gram – cell

wall?

What is the different chains of the gram- cell wall are joined together by DAP and D-alanine while the gram + chains join by a peptide

interbridge?

What is the gram – cell wall has only a few layers of peptidoglycan while there are many layers in the

gram + cell wall?

What is the gram – cell wall has 2 layers and the gram + has only one

layer?

What is the gram – cell wall has a periplasmic space

and porins(others but no space)

These are the 3 parts that make up LPS and this is

the part that faces the outside

What is lipid A, core oligosaccharides and O-linked oligosaccharides

(most outer part)?

This is what is recognized by Toll receptors.

What are Markers specific for a class of pathogens

(pathogen-associated molecular patterns)?

This is the location of toll receptors in the host cell.

What is either on the cell surface or

intracellular?
