give 5 examples of chemolithotroph types
nitrifying bacteria suphur oxdisers irn bacteria hydrogen bacteria carboylbacteria
give examples of conditions of extremophiles
themophiles >6.5 ->119.5
acidophile ph1
halophile 8m naoh
how is electron transport more complex in prokaryotes
what is this called
there are several different electron donors and several differetn electron acceptors
electron donors can go in at different points at nadh the dehydrogenase, the quinone poool, cyt c or cytochrome oxidase
energy dependent reverse e transfer
where do sulfobus live
hot sulfuric acid
what are the conditions inside hydrothermal vents
no light low 02 4 degree c high pressure 2.5km down black smokers = 400 degrees h2s and other minerals
what can survive in hydrothermal vent
rifitia pachyptilia
tube worm
with symbiotic bacteria
what is a trophosome
organ that houses bacteria that completely nourish the host
what do the symbiotic bacteria in tube worms do?
oxidise sulfer to make organis molecules host can use
what does the tube worms haemoglobin contain
specilises haemoglob contains 02 and h2s
what is nanoarcheam
marine archae discovered in hydrothermal vent
obligate symbiont on archae ignicoceus which is an thermophile with a peculiar genome 16srna is undetectable
given own phylum
where does chlorophyl depenedent oxygenic photosynthesis occur
in cyanobacterium
where does bacteriochlorophull depened anoxygenic photosynthesis occur
in purple and green bacteria
where does bacteriorhodpsin dependent photosyntehsis occur
in halobacterirum
do archea have a nucleys
no
how are archea identified
rRNA seq
