What is lithotrophy? A) breakdown of molecules using light energy B) oxidation of organic electron donors to CO₂ and H₂O C) photolysis of H₂S or H₂O coupled to CO₂fixation D) oxidation of inorganic electron donors such as Fe²⁺ using O₂ or anaerobic electronic acceptors E) none of the above

Question

Quizplus · Accepted Answer

Lithotrophy is the ability of microorganisms to use inorganic compounds as a source of energy. Option D describes the oxidation of inorganic electron donors such as FeS or S using O2 or anaerobic electronic acceptors, which is a common process in lithotrophic organisms. The other options describe processes that are not directly related to lithotrophy.
