W4-lecture 1: Metabolic diversity Flashcards
What is a primary producer?
A primary producer is an organism that use inorganic compound and turn it into organic compounds.
What is the other compound e.coli can reduce when there is no oxygen available
nitrate (NO3)
Where does the electron from cyanobacteria come from?
H2O
T or F : the carbon source of the photoautotrophs is CO2
T
T or F : the protons of the proton motor force accumulate in the stroma of the chloroplast
F
T or F : pseudomonas yield has much energy during the denitrification than the aerobic respiration of e.coli
true.
T or F : thylakoids membrane are only found in the eukaryotes.
false, they are found in cyanobacteria.
In which bacteria seen in class is present the chlorosome?
green sulfur bacteria and purple sulfur bacteria
T or F : the purple bacteria generates ATP with ATPase
true.
What is the electron source of the green sulfur bacteria?
H2S (sulfide)
What is the electron source of the purple sulfur bacteria?
H2S (sulfide)
T or F : the green sulfur bacteria can use organic compounds as a source of electron
false, but the purple sulfur can (in that case it is called purple non sulfur)
Name five organisms seen in class that uses light as a source of energy
- green sulfur bact.
- purple sulfur bact.
- purple non sulfur bact.
- cyanobacteria
- algeae
What is the difference between an anoxygenic and an oxygenic phototroph
creation of oxygen because the last compound to be reduced is oxygen (oxygenic) and no creation of oxygen (anoxygenic)
Where does oxygenic photosynthesis occurs in cyanobacteria?
cytoplasm
What is the type of reaction center of the green sulfur bacteria
Fe-s type
What is the type of reaction center of the purple sulfur bacteria
Q-type
What is the type of reaction center of cyanobacteria or algea?
there is two types of reaction center (Q-type in the PSII and Fe-s type in the PSI)
T or F : the nitrifying bacteria does the oxidation of ammonia to nitrite
True
What are the two types of nitrifying bacteria seen in class?
nitrobacter spp and nitrosomonas spp
complete : the nitrobacter oxidize ___ to ___
NO2 (nitrite) to NO3 (nitrate)
How is the NADH produced n the nitrifying bacterias?
by reverse electron flow
complete : the nitrosomonas spp oxidize ___ to ___
ammonia (NH3) to nitrite (NO2)
What is the final electron acceptor of nitrobacter spp?
oxygen
What is the final electron acceptor of nitrosomonas spp?
oxygen
____ release some methanogene while the ____ take the methanogen as a energy/electron and carbon source
methanogen
methanotroph
What is the electron acceptor of sulfur bacteria (thiobacillus spp)
oxygen
How is produced the NADH in sulfur bacteria thiobaccillus spp?
reverse electron flow
What are the two sources of energy and electrons of methanogens?
H2 and acetate
What are the two sources of carbon in methanogen
CO2 and acetate
What is the source of carbon and energy of methanotrops?
CH4
What is the full name of the enzyme rubisCO
ribulose bisphosphate carboxylase
What is the final molecule of the calvin cycle that will be used for biosynthesis?
fructose-6-phosphate
