3
What is the unusual fate of fermentation end products that are made in the cell?
They are excreted out of the cell
4
Why don’t eukaryotic cells have simultaneous transcription and translation like bacteria
eukaryotes do transcription and translation in separate places in the cell
5
In bacteria mutation can have the consequences of (select all that apply)
most are lethal to the off-spring and they die , many harmful , some mutation are neutral , some are beneficial
6
HGT transformation-DNA transfer by
DNA pickup from the environment
7
After conjugation between F+ E.coli and F- E.coli cell what happens to the F- cell
F become F+ fuse to the transfer of the plasmid into the F- cell
8
HGT conjugation-DNA transfer by
Cell to cell contact
9
HGT Transduction- DNA transfer by
Bacterial virus (phage) transfer
10
What is in the G- periplasm? (select all that apply)
digestive enzymes , peptidoglycan , receptors
11
Inclusion/storage granules in bacteria-what can be stored?
gases , glycogen , lipids/oils , phosphate , magnetic iron
12
Aspects of Bacterial endospores (select all that apply)
survival of harsh conditions , created by sporulation , producing cell dies , spores can survive boiling water
13
Many more carbons enter the Krebs cycle than the # of Carbons given off as CO2- What happens to all the carbon that doesn’t become CO2?
Used to make more carbon building blocks and more cells
14
In bacteria “Horizontal Gene transfer” refers to
genes physically passed to an existing cell
15
Gram + cell walls matched (select all that apply)
NAM-NAG fibers , teichoic acids , peptide cross links
16
Gram - Cell wall matches (select all that apply)
Monolayer peptidoglycan NAM-NAG fibers , periplasm , peptide crosslinks , o-polysaccharide , outer membrane , lipid A
17
Chemotaxis; (Select all that apply)
CCW flagella spin = run , runs = towards attractants , basal body is the anchor
18
Outer membrane (G-) components (select all that apply)
o-polysaccharide , endotoxin, porins/pores , lipid A
19
Bacterial cell DNA (all that apply)
Ciruclar molecule of double standard DNA , Refereed to as the genome , usually only has one copy , has no his tone proteins
20
Electron cannot exist free in the cell. How are they handled during metabolism? (Select all that apply)
carried by co-enzyme such as NAD+ and FAD , Passed onto cytochromes during electron transport , passed onto oxygen ad the final e- acceptor
21
Chemoisomosis in the cell (select all that apply)
Pumps H+ out of the cell , makes ATP from the H+ gradient , oxidizes NADH back to NAD+ so it can pick up more electrons
22
How does Chemisomosis create ATP? (Select all that apply)
electron movement creates H+ gradient outside of the cell , H+ enters cell at ATPase in the membrane, ATP made from ADP
23
What is the fate of the donor cell in Transformation?
the donor cell dies it Lyses
24
What is the fate of the donor cell in Conjugation?
the donor cell lives, its plasmid is copied
25
What is the fate of the donor cell in Transduction
the donor cell dies (from virus infection) and it is lysed by the virus
