A NEW VISION OF ENZYMATIC PROCESSES AND THE YIELD OF CEREALS WITH THE PARTICIPATION OF MOLECULAR OXYGEN IN THE CONTEXT OF THE NATIONAL INTERESTS OF UKRAINE
Oxygen is the elixir of life for all aerobic organisms on Earth. It makes up 21% of the air we breathe, but that wasn't always the case. Initially, our planet's atmosphere was full of carbon dioxide, so only primitive anaerobic organisms, which do not need oxygen for living, could survive....

Initially, our planet's atmosphere was full of carbon dioxide, so only primitive anaerobic organisms, which do not need oxygen for living, could survive.

| description |
Oxygen is the elixir of life for all aerobic organisms on Earth. It makes up 21% of the air we breathe, but that wasn't always the case. Initially, our planet's atmosphere was full of carbon dioxide, so only primitive anaerobic organisms, which do not need oxygen for living, could survive. But then a miracle happened: cyanobacteria, tiny organisms, began to use the energy of sunlight to assimilate carbon dioxide and water, a process now known as photosynthesis, which produces molecular oxygen from a water molecule as a by-product. The period that followed is known as the Great Oxygen Catastrophe, as the emergence and accumulation of a new two-atom molecule in the atmosphere led to the butterfly effect, an irreversible event that made our planet what it is today [1]. In turn, this event led to the emergence of multicellular life, which can exist and thrive on Earth with the help of oxygen. In addition to respiration, oxygen protects us from the Sun's harsh ultraviolet radiation through the Schumann-Runge absorption and in the 175–205 nm range and creates an ozone layer in the stratosphere that protects us from the softer UV rays of 240 nm.
Oxygen has been the subject of intense research for more than two centuries, ever since the Swedish chemist Scheele first obtained this pure gas by decomposing black magnesia. However, the mechanisms of reactions involving oxygen in living organisms are still not fully understood. It is now known that reactions of oxygen with organic compounds are forbidden by spin, but photosynthesis and respiration are vivid examples of how this prohibition can be overcome. The O2 molecule has two unpaired electrons (spins) on the outer electron shell, whereas almost all organic matter is diamagnetic and has zero spin.
How molecular oxygen overcomes spin prohibition during its activation by enzymes is discussed in this article. Particular attention is paid to understanding reaction mechanisms in living organisms, using photosynthesis and respiration as examples. Furthermore, the topical area of studying the mechanism of the Ribulose-1,5-bisphosphate carboxylase (RuBisCo) is emphasized, which offers the possibility of developing new approaches to increasing cereal yields for farmers. |
