Autotroph |
Organism that uses carbon dioxide as a carbon source |
|
Heterotroph |
Organism that reduces organic compounds as a carbon source |
|
Phototroph |
Organism that uses light for energy |
|
Chemotroph |
Organism that uses chemical sources for energy |
|
Lithotroph |
Organism that uses inorganic sources for electrons |
|
Organotroph |
Organism that uses organic sources for electrons |
|
Catabolism |
Synthesis of ATP in chemoorganotrophs |
|
Fermentation |
substrate acts as the electron donor, product is the terminal electron acceptor (net balance of oxidation and reduction between the reactants) |
|
Respiration |
requires an external electron acceptor. Oxygen most commonly used (aerobic respiration), but acceptor may alo be other compounds such as nitrate, iron, or sulfate (anaerobic respiration) |
|
Glycolysis |
conversion of organic molecules into pyruvate through oxidation of the substrate. Substrate-level phosphorlyation (ATP production) and reduction of coenzymes |
