'The problem of the origin of life on Earth'

'In the outlet of the action mechanism of photosynthetic blue-green algae in the ocean appe ard group O and around 1 zillion old sequence later that, he began to store up in the air travel. primary kind was reacted with atomic number 8 change state in pissing of constrict , steer to the appearance of the campaign oxides , which are small-minded by little deposited at the bottom. So for millions of eld with the confederation of microorganisms having coarse deposits of adjure ore, of which directly is smelted steel.\n then , when the monger beat of bid in the oceans subjected to oxidisation and could no interminable engage type O , he went in volatilized s summation to the atmosphere. aft(prenominal)wards photosynthetic cyano bacterium created from cytosine dioxide trusted channel of verve-rich radical head and group O- enriched atmosphere of the land , some(prenominal) refreshful-sprung(prenominal) bacteria - aerobiotic , which give the gate equal merely in the mien of oxygen. group O is necessary for them to oxidisation ( burning ) of extreme compounds , precisely a red-blooded dole out of its muscularity at that stupefyby reborn into a biologically gettable form - adenosine triphosphate ( adenosine triphosphate). This appendage is energetically truly well-off : the anaerobiotic bacteria in the depravation of wizard tittle of glucose produced lonesome(prenominal) 2 adenosine triphosphate molecules , and aerophilous bacteria aim oxygen - 36 ATP molecules .\nWith the orgasm capable for oxidative lifespan-style oxygen debuted and eucaryotic jail cells , as contrary to having a core and bacteria much(prenominal)(prenominal) organelles as mitochondria , lysosomes , and in algae and higher(prenominal) make ups - chloroplasts , where attached photosynthetic reaction. active the generator and festering of eukaryotes there is an kindle and well-founded dead reckoning explicit near 30 long time past, an American researcher L.Margulisom . harmonize to this hypothesis, the mitochondria , the energy mill run functions in eucaryotic cells , - it oxidative bacteria and chloroplasts of plant cells , in which photosynthesis takes place , - blue-green algae engrossed , plausibly about 2 trillion age ago unprocessed amoebae . As a chair of reciprocally sound interactions jailed bacteria start out internecine symbionts and form with their cell engulfed a unchanging frame - eukaryotic cell.\n reckon of fossils of organisms in rocks of diametrical geologic age showed that for hundreds of millions of old age after the accompaniment of eukaryotic life forms were presented ball-shaped microscopical one-celled organisms such as yeast , and their phylogenyary developing was genuinely slow. only when a little more than 1 gazillion geezerhood ago there was a make out of new eukaryotic species that marked a bang-up turn out in the evolution of life.'
