Ch 7

Question 1

Chemotoph - chemoautotroph

Answer 1

Energy source: chemical
Carbon source: co2

Question 2

Chemotroph - chemo heterotroph

Answer 2

Chemical energy source
Organic compounds

Question 3

phototroph- photoautotroph

Answer 3

Light source energy source

Question 4

Aerobic cellular respiration

Answer 4

Glycolysis
Transition step
Respiratory step
Molecular oxygen is the final electron acceptor of etc
Carbon is released as co2

Question 5

Additional uses of electron transport chain

Answer 5

Movement of flagella
Active transport system

Question 6

Electron transport chain varies

Answer 6

Both aerobic & anaerobic is possible

Question 7

Fermentation

Answer 7

Breaking down glucose via glycolysis
Does not require oxygen
There is no kreb cycle & no electron transport chain
Used when respiration is not an option
Fields 2 ATP
NADH is created

Question 8

amphibolic pathways

Answer 8

Metabolic pathways used in both anabolism and catabolism

Question 9

Anabolism (bio synthesis)

Answer 9

Requires an input of energy
Includes the synthesis of carbohydrates proteins, lipids, and nucleic acids using precursor monomers from existing catabolic pathways

Question 10

The end products of fermentation

Answer 10

Can help identify the bacteria and can be commercially valuable

Question 11

Gram staining

Answer 11

Crystal violet primary stain—-Iodine mordant—Alcohol decolorizer—- Safranin counter stain

Question 12

Making a bacterial smear an heat fixing a slide

Answer 12

Aseptically transfer broth bacterial culture to a clean slate allowed to air dry 5 to 10 minutes
Heat fixed slides by moving slides through the picture of flame 23 times
Never heat fixed sweat like
The purpose is of heat fixing is to kill and immobilize bacteria on the side

Question 13

Serial dilution

Answer 13

Are used to create decreasing concentrations of the original sample
When is better dilutions into an iPad for an 11 to go you look for colony forming units between 30 colonies and 300 colonies are accountable

Question 14

Viber plate count

Answer 14

Account available or lifestyles

Question 15

Dilute the sample through a series of delicious cultivation

Answer 15

Put 9 mL of Nadiaa and Epdi test tubes one through four
Take one milliliter from the original bacteria faces to two and so on and so forth

Question 16

Results of expressed colony forming units per milliliter

Answer 16

CFU over milliliter

Question 17

Dilutions calculation

Answer 17

volume transferred over total volume

Question 18

What are the two common methods of inoculating plates for viable counts?

Answer 18

Spread plate method and pour plate
Both message you serial dilution’s as a first step today with the original sample in a series of dilutions s

Question 19

Gene regulation

Answer 19

Transcription, post transcriptions, translation, post translation

Only done when necessary

Question 20

Operons

Answer 20

Genes with related functions that are transcribed together into One mRNA transcript
Controlled by 1 promoter
all turned on or off together
Found in bacteria, archaea & in a few eukaryotic
This mRNA transcript is called polycistronic

Question 21

DNA promoter

Question 22

DNA operator

Answer 22

Regulatory DNA region where gene repressor or activator cm bind

Question 23

Lac operon

Answer 23

Inducible ( default is off )
Makes enzyme to break down glucose
Turns on when there are lactose enzyme presents

Question 24

Aerobic cellular respiration

Answer 24

Glycolysis
Transition step & kreb’s cycle/ tricarboxylic acid
Respiratory chain or election transport chain

Question 25

Electron transport chain of prokaryotes varies tremendously

Answer 25

Even single species can have several alternate carriers this allows prokaryotes to grow in many different growth conditions.
