Energy Acquisition Summary
What will be an ideal response?
-Organotrophy: organic compounds donate electrons
----fermentation: catabolism (electron acceptor:organic)(systems for energy acquisition-glycolysis and other catabolism)
----organic respiration (catabolism with inorganic or small organic electron acceptor)(electron acceptor: O2, and NO3-, SO42-, Fe3+, prother) (systems for energy acquisition: glycolysis and other catabolism TCA cycle, electron transport system)
-Lithotrophy: inorganic compounds donate electrons
----lithotrophy or chemoautotrophy (electron acceptor: O2 or NO3-) (systems for energy acquisition: electron transport system)
----methanogenesis (electron acceptor: CO2)(systems for energy acquisition: methanogenesis)
-Phototrophy: light absorption provides electrons
----photoautotrophy: light absorption drives CO2 fixation (systems for energy acquisition: Photosystem I or II)
----photoheterotrophy: catabolism with light absorption (examples of energy-yielding reactions: photolysis of H2S, HS-, or small organic molecules, light-driven H+ pump or Na+ pump) (systems for energy acquisition: photosystem I or II, Bacteriorhodopsin or proteorhodopsin)
