光合生物出现后的氧化-还原平衡（The photosynthetic oxidation biological appears after reduction equilibrium.） The principle of Earth Science: oxidation reduction equilibrium after the emergence of 33 photosynthetic organisms Guangdong Ocean University Yong Yan Liao (e-mail: rock6783@126.com) Because the original atmosphere of the earth, although the reduction is far lower than the atmosphere of the universe, but it is still a strong reducing environment. So, first appeared on the earth by anaerobic photosynthetic organisms, is certainly non photosynthetic life by anaerobic photosynthetic organisms (such as sulfur bacteria, photosynthetic bacteria) gradually evolved, it certainly is anaerobic organisms. When the earliest photosynthetic organisms appeared, they used photosynthesis to convert carbon dioxide and hydration into organic compounds. From the above analysis we can see that carbon dioxide and water are redox neutral substances, and finally, the strong reducing organic compounds are synthesized, which reduce the oxidation of the whole system and increase the reducibility. The oxidation - reduction system in order to maintain the balance and stability, to release strong oxidizing substances as make up, so, in photosynthesis to organic synthesis of carbon dioxide and water at the same time, must release oxygen and other strong oxidizing substances. The initial emergence of photosynthetic organisms, itself is still does not have the ability to obtain energy by oxygen oxidation of organic matter, which itself is still anaerobic, oxygen is toxic to it, but if it is through photosynthesis, carbon dioxide and water into strong reductive organic compound, it must release oxygen to compensate redox equilibrium. So, these creatures, may use in the environment can be a mechanism of oxygen produced by photosynthesis in consumption, the oxygen produced by photosynthesis, in vivo or in the surrounding environment does not increase and accumulation, so as not to cause harm to yourself.
