W4-lecture 1: Metabolic diversity

Question 1

What is a primary producer?

Answer 1

A primary producer is an organism that use inorganic compound and turn it into organic compounds.

Question 2

Answer 2

nitrate (NO3)

Question 3

Where does the electron from cyanobacteria come from?

Answer 3

H2O

Question 4

T or F : the carbon source of the photoautotrophs is CO2

Answer 4

T

Question 5

T or F : the protons of the proton motor force accumulate in the stroma of the chloroplast

Answer 5

F

Question 6

T or F : pseudomonas yield has much energy during the denitrification than the aerobic respiration of e.coli

Answer 6

true.

Question 7

T or F : thylakoids membrane are only found in the eukaryotes.

Answer 7

false, they are found in cyanobacteria.

Question 8

In which bacteria seen in class is present the chlorosome?

Answer 8

green sulfur bacteria and purple sulfur bacteria

Question 9

T or F : the purple bacteria generates ATP with ATPase

Answer 9

true.

Question 10

What is the electron source of the green sulfur bacteria?

Answer 10

H2S (sulfide)

Question 11

What is the electron source of the purple sulfur bacteria?

Answer 11

H2S (sulfide)

Question 12

T or F : the green sulfur bacteria can use organic compounds as a source of electron

Answer 12

false, but the purple sulfur can (in that case it is called purple non sulfur)

Question 13

Name five organisms seen in class that uses light as a source of energy

Answer 13

1. green sulfur bact.
2. purple sulfur bact.
3. purple non sulfur bact.
4. cyanobacteria
5. algeae

Question 14

What is the difference between an anoxygenic and an oxygenic phototroph

Answer 14

creation of oxygen because the last compound to be reduced is oxygen (oxygenic) and no creation of oxygen (anoxygenic)

Question 15

Where does oxygenic photosynthesis occurs in cyanobacteria?

Answer 15

cytoplasm

Question 16

What is the type of reaction center of the green sulfur bacteria

Answer 16

Fe-s type

Question 17

What is the type of reaction center of the purple sulfur bacteria

Answer 17

Q-type

Question 18

What is the type of reaction center of cyanobacteria or algea?

Answer 18

there is two types of reaction center (Q-type in the PSII and Fe-s type in the PSI)

Question 19

T or F : the nitrifying bacteria does the oxidation of ammonia to nitrite

Question 22

How is the NADH produced n the nitrifying bacterias?

Answer 22
