MICB 201 Chapter Notes - Chapter 20: Nitrogen Assimilation, Glutamine, Light-Independent Reactions
Document Summary
As long as you got light, doesn"t matter if aerobic or anaerobic. Big primary producer in the ocean and produces 20% of the oxygen on earth. Chemosynthesis is not about getting energy from chemicals, it is about converting inorganic carbon to synthesis organic material for energy. Symbiotic relationship between tube worm and bacterial symbionts. Tube worm provides o2, h2s, co2 to bacteria. Oxygen: comes from photosynthesis (dependent on sunlight for its production, produced up higher in the ocean by plants and cyanobacteria) Major ecological role of bacteria: to take elements to convert inorganic to organic sources which could be used by plants (it"s what they do naturally, they don"t do it for the plants) We have to understand what they are eating and why they make acid. Live in environments where energy, and major bioelements are easily accessible. H+ is produced as waste during oxidation of nutrient.
