怎样区分厌氧,好氧,异养,自养(国外英文资料) How do you tell the difference between anaerobic, aerobic, heterotrophic, autotrophic Two types of assimilation In the process of assimilation, the organism can not use the inorganic material to make organic matter, and the metabolism can be divided into self-feeding and heterotrophic. Autotrophic directly from the environment to absorb inorganic, green plants through photosynthesis, will create into complex organic matter, inorganic matter and storing energy, to maintain its own life activity, and metabolism of such type belongs to autotrophic. A few species of bacteria, cant for photosynthesis, and able to take advantage of external environment of some inorganic oxide at the release of energy to make organic matter, and relies on the oxidative decomposition of organic matter during the release of energy to sustain their life activities, the synthetic effect called can synthesis effect. Nitrifying bacteria, for example, can be in the soil of ammonia (NH3) converted to nitrite (HNO2) and nitric acid (HNO3), and use the energy release by the oxidation process for synthesis of organic compounds. Anyhow, organisms in the process of assimilation, to transform from the environment to absorb inorganic as its material composition, and storing energy, metabolism of this type are called autotrophic. Heterotrophic type of people and animals cant photosynthetic, like a green plant, cant for like nitrifying bacteria can synthesis effect, they can only rely on ready-made organic matter in the external environment intake to maintain its own life activity, the metabolism of such types of heterotrophic growth type. In addition, the fungi, most species of bacteria that live in the camp or parasitize, are also heterotrophic. To sum up, organisms in the process of assimilation, the intake from the outside environment and the ready-made material composition, organic matter into their own and store energy, metabolism of this type is called heterotrophic type.
