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
