Lesson 6-Cell inclusion, endospores, and taxes

what does taxes mean?

plural word for tax; directional movement of cell towards attractions, away from repelent

Name the 5 bacterial cell surface structures:

Fimbriae, Pili, Capsules, slime layers, and paracrystalline surface layers

Describe the differences between fimbriae and pili:

fimbriae: short but numerous

pili: long, but not as many

What part of the bacterical cell surface structure affect the pathogenicity of cells?

capsules and slime layers

capsules and slime layers are usually composed of _________________.

polysaccharide

What does S-layers stand for in bacterical cell surface strucutre?

and what is it made of

Paracrystalline surface layers; made of proteins or glycoproteins

What are one of the main roles of pili and fimbriae?

binding/attachment

difference between fimbriae and flagella:

frimbriae: short, hair-like; adhesion

flagella: longer; locomotion

_______ are used during conjugation(for cell communication) and may have phage receptors.

pili

_________ pili are found only at poles and some role in twitching motility.

Type IV

If you loose the ability to make a capusle you also loose the ability to do what?

loose the ability to make a disease

Capsules aid in __________ to surfaces and help pathogens avoid ___________.

adhesion; phagocytosis 

Out of all the pathogens that have capsules, which one has a protien capsule instead of polysaccarhide?

bacillus anthracis

_____________ surface layers are two-dimenstional lattice of protiens or glycoprotiens.

Paracrystalline

Archaea often have what type of layers instead of a cell wall?

S-layers

Although they lack a lipid, how could the S-layer plat a role similat to that of outer membrane?

S-layer acts as a periplasmic membrane which contains porins(holes for small molecules to pass)

What is the periplasm?

between the inner/outer membrane

what are the 2 forms of carbon storage polymers?

lipid storage(poly-B-hydroxybutyrate) and polysaccharides (glycogen)

what form of carbon storage polymer has higher energy density properties? also explain what higher energy density is.

lipid storage; C4 form; poly-B-hydroxybutyrate. higher-density storage takes up less space but has more energy

poly-B-hydroxybutyrate
