3 Domains of Life


What is function of cell membrane?



1a

Archaea, Eukarya, and Bacteria

1b

(9+2) structure

2a

describes structure of cilia and flagella; 9 pairs of microtubules surrounding a central pair

2b

ABC Transport System 3a

-ATP-binding cassette

-Three components: substrate-binding protein/periplasmic binding,

membrane-integrated transporter, and ATP-hydrolyzing protein

-high-substrate affinity We also discuss several other topics like What factors affect diffusion rate?

-found in both Gm- and Gm+3b

amphitrichous

4a

tufts of flagella at both poles of organisms

4b

Archaeal Flagella vs. Bacterial 5a

-uses several proteins unrelated to flagellin


What is affinity in biology?



Don't forget about the age old question of What is skaldic poetry?

-uses ATP rather than PMF 5b

archaeal membranes 6a

-contain ether bonds between glycerol and hydrophobic side chains

-side chains are repeating subunits of isoprene

-composed of glycerol diethers and phytanhyl groups (20C)(bilayer) or diglycerol tetraethers and biphytanyl groups (monolayer)6b

autoclave

7a

large, pressurized chamber using moist heat; used for sterilization

7b

bond energy

8a

anhydride > thioester > ester

example compounds:

phosphoenolpyruvate

(anhydride) > ATP (2 anhydride and one ester bond)

8b

Bright-Field Microscopy 9a


How do archaeal flagella differ from bacterial flagella?



only for organisms with pigmentation that sets them apart from the background

9b

capsule Don't forget about the age old question of What are the theories of law?

10a

-tight matrix that blocks out small particles like stains -often stained with India ink most are firmly attached to cell wall

10b

catabolism

11a

breaking down; energy yielding reactions Don't forget about the age old question of Why do we calculate average value?

11b

coenzyme

12a

non-protein components of enzymes

-ex: nicotinamide

12b

cofactor

13a

inorganic compounds that aid enzymes

13b

complex media

14a

uses digests of microbes, animals, or plants or their products

-exact composition is

unknown

14b

Components of Flagellar Rotary Motor

15a

rotar moves; includes central rod and rings

stator is static; includes Mot proteins

15b

Confocal Scanning Laser Microscopy

16a

-laser source and fluorescent microscope

-3D image with only one plane in focus at one time

-layers can be assembled to give 3D image

16b

conjugation

17a

process by which bacteria exchange genetic

information

17b

Dark-Field Microscopy 18a

-uses light that reaches specimen from only the sides If you want to learn more check out What are constellations?

-light is scattered by the

specimen making it appear light on a dark background

18b

defined media

19aIf you want to learn more check out How does democracy work?

Exact composition is known 19b

diaminopimelic acid (DAP) 20a

amino acid analog found in PG

20b

Differential Interference Contrast Microscopy (DIC)

21a

-produce polarized light in a single plane and goes through a prism -differences in the refractive indices of the material affect the rejoined two beams of light causing interference which enhances cell structures 21b

differential media

22a

uses and INDICATOR to reveal whether a particular chemical reaction has occured

22b

Differential Stains

23a

shows different types of cells in different colors

-ex: Gram stain

23b

dipicolinic acid

24a

in core of endospore

helps push out water

alongside calcium ; appears necessary in spores but not in vegetative cells

24b

endergonic reaction 25a

requires energy input delta G is positive

25b

Endospore Formation and Germination

26a

1. activation: usually heating at an elevated temperature

2. germination: loss of resistance to heat and chemicals and refractile nature 3. out grow: visible swelling due to water uptake and synthesis of RNA, DNA, protein

26b

endospores

27a

-highly differentiated cells that are highly resistant to heat, chemicals, and radiation -dormant

-very refractile

27b

Endospore Structure 28a

1. exosporium- outermost thin layer of protein

2. spore coat- multiple; within the exosporium with spore-specific proteins 3. cortex- loosely cross-linked PG

4. core- contains core wall, membrane, cytoplasm, cell components including dipicolinic acid28b

endosymbiont hypothesis 29a

-chloroplasts, mitochondria, and hydrogenosomes are likely

descendants of once free-living bacteria

-each has its own genome and ribosomes, genetically similar rRNA to bacteria29b

energy storage polymers 30a

glycogen, poly-β

hydroxybutyrate, and elemental sulfur

30b

enriched media

31a

adds additional nutrients such as BLOOD or SERUM to a complex base

31b

Essential cations and anions for most organisms

32a

potassium, magnesium, calcium, and sodium

32b

essential nutrients for all organisms

33a

Selenium, Nitrogen, Carbons, Hydrogen, Oxygen,

Phosphorous, Sulfur (SeN CHOPS)

33b

ester linkages

34a

bacteria and eukarya have ester linkages between the fatty acids and glycerol

34b

eukaryotic flagellar movement

35a

propel in whip-like motion -occurs to microtubules sliding against one another; dynein uses ATP to drive motility

35b

Ferdinand Cohn

36a

founder of bacteriology 36b

Ferric

37a

F^3+ (threesome? ICK!) 37b

free energy

38a

-energy available to do work -designated by a G

38b

Functions of Cytoplasmic Membrane

39a

-permeability barrier -protein anchor

-energy conservation 39b

gelling agent

40a

solidifies liquid cultures 40b
