BACTERIAL METABOLISM

Question 1

what are the anabolic reactions?

Answer 1

synthesis of all cell structures

synthesis of functional proteins

synthesis of cellular materials

Question 2

what are the catabolic reactions?

Answer 2

breakdown of organic substrates

provision of organic substrates

provision of energy

Question 3

what are the ways ATP can be formed?

Answer 3

substrate level phosphorylation

transfer of inorganic phosphate to ADP-

Question 4

this pattern of energy yielding metabolism is also known as classic glycolysis for glucose substrate?

Answer 4

Embden-Meyerhof-Parnas Pathway which yields 2 pyruvate that become 2 lactate

homolactate, ok for bacteria but not for eukaryotes

Question 5

this is another means of fermentation that is homolactate producing 1 ATP? E. coli uses this

Answer 5

Entner-Doudoroff pathway

Question 6

this is another means of fermentation used by E. coli as well also known as alcohol with CO pathway (Mixed acids pathway)?

Answer 6

Heterolactate pathway

Question 7

some fungi use this type of fermentation?

Answer 7

ethanol

Question 8

streptococcus and the species of lactobacillus use this type of fermentation?

Answer 8

lactate

Question 9

clostridium propionecium
propiobacterium
corynebacterium diphtheria
neisseria

use this type fo fermentation

Answer 9

propionate

Question 10

eschierechea
shigella

use this type of fermentation?

Answer 10

mixed acid

Question 11

butyribacterium
clostridium
neisseria

use this type of fermentation?

Answer 11

butanol-butyrate

Question 12

this type of laboratory test collects gas from the organism and pushes it up, and so if there is O2 production the tube is pushed up?

Answer 12

durham tube test

Question 13

for the bacteria that use aerobic respiration, how many ATP are produced?

Answer 13

38 ATP in bacteria, 36 in animals

Question 14

anaerobic fermentation produces how many ATP?

Answer 14

2 ATP

Question 15

anaerobic respiration produces how many ATP?

Answer 15

24-36 ATP

Question 16

aerobic respiration produces how many ATP?

Answer 16

38 ATP

Question 17

these bacteria type use the ETC and oxygen?

Answer 17

obligate aerobe

Question 18

these bacteria type can function with oxygen and without?

Answer 18

facultative organisms

Question 19

this bacteria type uses the Embden Myerhoff pathway or NO3 producing 16-36 ATP

Answer 19

obligate anaerobe (poisoned by oxygen)

Question 20

what is the purpose of the hexose monophosphate shunt?

Answer 20

when there is enough for energy purposes and so this pathway is used for NADPH biosynthesis, ribose sugars for nucleic acid synthesis
