Chemotroph
Videos
A chemotroph is an organism that obtains energy by the oxidation of electron donors in their environments. These molecules can be organic or inorganic. The chemotroph designation is in contrast to pho

Chemosynthesis
Videos
In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules and nutrients into organic matter using the oxidation of inorganic compounds or ferrous ions as
Chemotroph
…examples of chemotrophic organisms include iron-oxidizing bacteria and methanogenic archaea. Chemoautotrophs are autotrophic organisms that can rely on chemosynthesis, i.e. deriving biological energy from chemical reactions of environmental inorganic substrates and synthesizing all necessary organic compounds from…
