So today we will introduce you top 10 fact about Google that you may not know.
The meteorites, which brought with itself the molecules, allowed to reserve energy could become batteries for the first organisms on Earth. Each organism has such built-in batteries, after all the energy received with food, not always is required at once and completely. At the heart of such organisms is phosphorus, but early forms of life had to it no access, because this element was hidden deeply in minerals. The stones pouring from the sky helped to solve a problem. According to Terry Ki from Great Britain University, the first source of energy could be pyrophosphite, consisting of phosphorus, oxygen and hydrogen. This substance is similar on the chemical properties to ATF and thus more reactive, that is enzymes aren’t necessary to it. Ki and his colleagues studied one Siberian meteorite, which has a phosphorus source. Fragments of a heavenly stone dipped into acidic water from volcanic ponds of Iceland, which is considered analog of the water existing on primitive Earth. Four days later samples of a meteorite allocated a large amount of phosphite. Having dried, it turned in pyrophosphite. As we see, this substance is formed very simply. Unfortunately conclusions caused an ambiguous assessment. The biggest problem is that all modern organisms use for energy accumulation by source of phosphate, instead of phosphites. The pyrophosphate reacts with water, instead of is dissolved in it, as pyrophosphite. Scientists prefer a pyrophosphate, because it is simpler. According to the scientitsts, there is no other argument in favor of such choice. The pyrophosphite could be the predecessor of a pyrophosphate: it used until life didn’t acquire the molecular equipment, which has allowed it to work with phosphates. During the further experiments, which results aren’t published yet, the group found out that pyrophosphite easily turns into a pyrophosphate.
