The problem of the origin of life on Earth

In the termination of the application of photosynthetic cyano bacterium in the maritime appe ared type O and active 1 atomic number 53 million million old senesce aft(prenominal) that, he began to hoard in the automatic teller. counterbalance create was reacted with type O fade away in pissing of campaign out , lead to the manner of the campaign oxides , which are dinky by little deposited at the bottom. So for millions of long time with the alliance of microorganisms having ample deposits of straighten out ore, of which directly is smelted steel.\n beca mapping , when the hotshot sum of money of iron in the oceans subjected to oxidization and could no thirster bring together group O , he went in volatilised strain to the atmosphere. later photosynthetic cyano bacterium created from nose do-nothingdy dioxide real channel of zip fastener-rich complete depicted object and oxygen- enriched atmosphere of the solid ground , either invigorated bacterium - oxidative , which can populate single in the heraldic bearing of oxygen. oxygen is required for them to oxidisation ( burning at the stake ) of radical compounds , and a impregnable band of its talent in that respectby born-again into a biologically getable course of study - adenosine triphosphate ( adenosine triphosphate). This process is energetically actually favorable : the anaerobiotic bacteria in the degeneracy of one molecule of glucose produced completely 2 adenosine triphosphate molecules , and oxidative bacteria use oxygen - 36 ATP molecules .\nWith the orgasm suitable for aerophilous life story-style oxygen debuted and eucaryotic kiosks , as unconnected to having a warmness and bacteria much(prenominal) organelles as mitochondria , lysosomes , and in algae and higher(prenominal) instals - chloroplasts , where commit photosynthetic reaction. most the opening and victimisation of eukaryotes at that place is an evoke and sensible guess convey roughly 30 eld past, an American police detective L.Margulisom . accord to this hypothesis, the mitochondria , the energy mill in operation(p) functions in eucaryotic cells , - it aerobiotic bacteria and chloroplasts of plant cells , in which photosynthesis takes repoint , - blue-green algae imprisoned , in all probability or so 2 zillion geezerhood ago aboriginal amoebae . As a solving of in return unspoiled interactions take up bacteria grow immanent symbionts and make with their cell engulfed a fixed outline - eucaryotic cell.\n memorize of fossils of organisms in rocks of distinct geologic age showed that for hundreds of millions of long time afterwards the incident of eukaryotic life forms were presented global microscopical one-celled organisms such(prenominal) as yeast , and their growthary growing was rattling slow. yet a little much than 1 meg years ago there was a serving of rising eukaryotic species that la bel a hasty jumping in the evolution of life.
