chemosynthesis

 [ke″mo-sin´thĕ-sis]
the building up of chemical compounds under the influence of chemical stimulation, specifically the formation of carbohydrates from carbon dioxide and water as a result of energy derived from chemical reactions. adj., adj chemosynthet´ic.

chemosynthesis

(kē′mō-sĭn′thĭ-sĭs, kĕm′ō-)
n.
The synthesis of organic compounds by certain bacteria, especially in deep-sea hydrothermal vents, using energy obtained from the chemical oxidation of simple inorganic compounds. Chemosynthesis is thought to have been used by the first forms of life on Earth.

chemosynthesis

the process of obtaining energy and synthesizing organic compounds from simple inorganic reactions. This is brought about by special methods of respiration involving the oxidation of inorganic compounds such as iron, ammonia and hydrogen sulphate, and is carried out by several kinds of CHEMOAUTOTROPHIC bacteria. See AUTOTROPH, NITROGEN CYCLE.
