摘要: Plants and cyanobacteria capture the light of sun utilize its energy to synthesize organic compounds from inorganic substances, such as CO 2 , nitrate, sulfate make their cellular material; they are photoautotrophic. In photosynthesis photon splits water into oxygen hydrogen, latter bound NADPH. This process, termed reaction takes place in photosynthetic centers embedded membranes. It involves transport electrons, which is coupled synthesis ATP. NADPH ATP consumed a so-called dark carbohydrates . The plants created biomass on earth, including deposits fossil fuels atmospheric oxygen. Animals dependent supply other substances food; heterotrophic. They generate required for life processes by oxidizing biomass, has first been produced plants. When consumed, formed. follows that captured also source animals.
