respiration and growth of eubacteria

Question 1

how can eubacteria be grouped?

Answer 1

according to respiration and modes of nutrition

Question 2

obligate aerobes

Answer 2

must have oxygen to survive

Question 3

obligate anaerobes

Answer 3

grow in environments without oxygen

Question 4

facultative anaerobes

Answer 4

can survive and grow with or without oxygen

Question 5

what is fermentation?

Answer 5

when oxygen is absent, both obligate and facultative anaerobes obtain energy by this process

Question 6

what does fermentation produce?

Answer 6

carbon dioxide and alcohol

Question 7

do all bacteria produce the same compounds from fermentation?

Answer 7

no

Question 8

what are the two classifications of eubacteria by nutrition?

Answer 8

autotrophs

heterotrophs

Question 9

what are three types of autotrophs?

Answer 9

cyanobacteria
purple bacteria
chemosynthetic

Question 10

how do autotrophs get food?

Answer 10

they produce their own food

Question 11

cyanobacteria

Answer 11

can perform photosynthesis

Question 12

purple bacteria

Answer 12

photosynthesis (in low light)

Question 13

chemosynthetic

Answer 13

makes food from carbon dioxide using energy from chemical reactions

Question 14

how do heterotrophs (most bacteria) get food?

Answer 14

they cannot make it

Question 15

what are three types of heterotrophs?

Answer 15

saprophytes (decomposers) feed on dead matter

Question 16

parasite

Answer 16

harmful effect on host (pathogenic)

Question 17

nitrogen fixers

Answer 17

live in plant roots, but supply plant with useable nitrogen
