what are the types of prokaryotic cells

archea and bacteria 

100

bacteria has hopanoids in their cell wall. What type of structural aiding molecule does archea have?

Neither sterols or hopanoids. They have something else

100

which one, gram positive or gram negative, has an outer membrane?

gram negative

100

why are carbon atoms so important

they are the building blocks for all cells

100

Why NAD+/NADH is sometimes not an effective electron carrier

because they are sometimes less electronegative than their electron source for chemolithrotropic anaerobic respirator

200

how do prokaryotic cells differ from eukaryotic cells

  • Ribosomal DNA sequence is different 

  • Cell wall structural differences 

  • Cell membrane structural differences

  • Chromosomal dna is different 

200

what type of link between the phospholipid head and tail does archea have

ether link

200

which one has an paraplasmic space

gram negatives

200

why is iron and magnesium important for all cells

they are cofactors for enzymes 

200

what electron carrier might chemolithrotropic anaerobic respirators use

CoQ and/or Cyt C

300

what shapes do coccus and bacillus make? and what arrangements can they make? 

Coccus is spherical shaped and bacillus is pill shaped. They can make mono, diplo, staphlo, and strepto arrangements.

300

do archea have peptidoglycan cell walls?

no

300

which one has many layer of peptidoglycan? 

gram positive

300

what is a chemoorganotroph that performs aerobic respiration

the electron source is organic and the electron acceptor is O2

300

what is the process of Butanediol fermentation

pyruvate looses a carbon → combines those 2 carbon molecules to a 4 carbon molecule called acetoin → donates electron and proton → butanediol

400

what structures do all prokaryotes have

  • Cell wall = protective barrier 

  • Cytoplasmic membrane = encloses cytoplasm 

  • Cytoplasm = gel like material inside of cell

  • Ribosome = protein synthesis 

  • Chromosomal DNA = all the genes they need (it’s circular)(only one chromosomal dna)

  • Inclusion = storage granule 

  • Cytoskeleton = provides structure 

400

what is the structure of peptidoglycan 

alternating

  • NAG= N-acetylglucosamine

  • NAM= N-acetylmuramic acid




400

what structures are unique to gram negatives?

lipopolysaccharides, lipoproteins, and porins

400

Which pathway produces NADPH; also, what is NADPH used for

it's produced in the pentose phosphate chain and is used to power anabolic reactions

400

what is the electron source for green bacteria 

H2S or H2

500

what is proton motive force

sending out protons out of the cell → goes back into cell carrying solute inside (lactose solute for example)

500

eukaryotes have ATP synthase in their mitochondrian cell membranes. Does bacteria have ATP synthase? is so where is it located?

Bacteria have ATP synthase and it's in their cell wall
500

which one is bad at holding die and why?

gram negatives because they only have two layer of peptidoglycan 

500

how can cellulose be broken down and at what step of making ATP can it be incorporated. 

it's broken down by cellulase. It's glucose molecules can go into the start of glycolysis. 

500

what is the characteristic of Aerotolerant bacteria

cannot use O2 as final electron acceptor but can survive exposure to O2
