The energy source of chemical energy synthesis is mainly from sunlight, which converts solar light energy into chemical energy of organic matter and releases oxygen at the same time. In the process of chemical energy synthesis, green plants absorb sunlight through chlorophyll and convert light energy into chemical energy. In this process, high-energy electrons are generated, which are used to convert carbon dioxide and water into organic matter and release oxygen. The organic matter in this process is usually glucose and starch, while oxygen is a by-product.
Chemical synthesis is one of the most important biochemical processes in nature and the basic way to maintain life. Through chemical synthesis, plants and other autotrophs can use sunlight to produce organic substances and provide food and energy for other organisms. In addition, the oxygen produced in chemical synthesis is of great significance for maintaining the oxygen balance on the earth and the ecological balance of the biosphere.
In the natural biological process of chemical synthesis, the synthesis of organic matter not only needs the energy of sunlight, but also needs the participation of carbon dioxide, water and some trace elements. Among them, carbon dioxide comes from the air in the atmosphere, and water is absorbed from the soil through plant roots.
In photosynthesis, the energy of sunlight is transmitted in chloroplasts, and then the electrons in pigment molecules are activated, making them transition to high-energy states, and finally transmitted to NADPH and ATP. These two high-energy compounds assist the fixation and reduction of CO2, and produce products that provide chemical potential energy for organic substances such as glucose. This process also involves the participation of many enzymes and the coupling of multi-step reactions, forming a complex reaction network.
Chemical synthesis plays a very important role in the ecosystem because it converts solar energy into usable biological energy. Organic matter produced by chemical synthesis of green plants is the main energy source of other organisms in the ecosystem, and also plays an important role in absorbing carbon dioxide and producing oxygen. In addition, chemical energy synthesis also provides a wide range of applications for agriculture and industry, such as the production of agricultural products and biomass fuels.
Introduction of autotrophs
Autotrophic organisms refer to those organisms that synthesize organic compounds through their own biochemical processes (such as photosynthesis and petrochemical synthesis) without looking for organic substances in food. In this life form, they do not rely on other organisms to provide energy and nutrients for survival and growth.
Autotrophic organisms can be divided into two types according to their biochemical pathways: photoautotrophic and chemoautotrophic. Photoautotrophs synthesize organic compounds such as glucose through photosynthesis. These organisms (such as plants, algae and some bacteria) use chlorophyll and other photosensitive organelles in their cells to capture solar energy to promote photosynthesis and convert solar energy into biomass and chemical energy. Chemotactic autotrophs synthesize organic compounds from inorganic compounds through chemical reactions, such as sulfur oxide, iron or ammonia oxidation.
Autotrophic organisms occupy a very important position in the earth's ecosystem, and they have made a key contribution to the stability of the whole ecosystem. Plants synthesize organic matter through photosynthesis, providing food sources and nutrients for other organisms; Microbes, on the other hand, use their own chemical synthesis ability and innate adaptability to life to survive and reproduce. Self-help organisms also play a role in solving many global problems today, such as producing energy for human beings, cleaning the environment and treating diseases.
