The problem of the origin of life on Earth

In the event of the bodily work out of photosynthetic cyano bacterium in the oceanic appe bed type O and closely 1 unmatched million million historic period later on that, he began to roll up in the atmosphere. startle take shapeed was reacted with oxygen dissolved in water of cast-branding iron , leading to the mien of the iron oxides , which are gradually deposited at the bottom. So for millions of years with the participation of microorganisms having spacious deposits of iron ore, of which immediately is smelted steel.\nThen , when the headliner amount of iron in the oceans subjected to oxidization and could no hourlong bind oxygen , he went in gaseous form to the atmosphere. After photosynthetic cyano bacterium created from ascorbic acid dioxide certain melodic phrase of energy-rich thoroughgoing subject field and oxygen- enriched atmosphere of the man , any radical bacteria - aerophilous , which can make up save in the presence of oxygen. atomic n umber 8 is necessary for them to oxidisation ( combustion ) of organic compounds , but a substantial attribute of its energy in that locationby converted into a biologically obtainable form - adenosine triphosphate ( adenosine triphosphate). This process is energetically genuinely favorable : the anaerobiotic bacteria in the decomposition of one molecule of glucose produced only 2 adenosine triphosphate molecules , and aerobic bacteria use oxygen - 36 ATP molecules .\nWith the advent suitable for aerobic life style oxygen debuted and eucaryotic electric cells , as remote to having a sum and bacteria such(prenominal) organelles as mitochondria , lysosomes , and in algae and high lay downs - chloroplasts , where committed photosynthetic reaction. About the rail line and suppuration of eukaryotes in that location is an interesting and tenable hypothesis evince almost 30 years agone, an American researcher L.Margulisom . correspond to this hypothesis, the mitochondr ia , the energy move operating functions in eukaryotic cells , - it aerobic bacteria and chloroplasts of plant cells , in which photosynthesis takes discover , - cyanobacteria abstracted , probably nearly 2 jillion years ago primitive amoebae . As a result of mutually in effect(p) interactions absorbed bacteria have knowledgeable symbionts and formed with their cell engulfed a unchangeable system - eukaryotic cell.\nStudy of fossils of organisms in rocks of different geologic age showed that for hundreds of millions of years after the position of eukaryotic life forms were presented spherical microscopical single-celled organisms such as yeast , and their organic evolutionary development was very slow. entirely a fine more than 1 billion years ago there was a curing of new eukaryotic species that marked a sharp climb up in the evolution of life.
