(pages 695-699; 622-624; 643-644; 597; 699-701; 602-609; 725-730; 701-702) Unit 4: biogeochemical cycling: the major source and sinks for carbon are co2 and ch4, carbon can be found in the atmosphere, the land, the oceans, and other aquatic environments, sediments and rocks, and biomass. Macromolecules from dead organisms find their way into the anoxic habitats. Following hydrolysis, the monomers are excellent electron donors for energy metabolisms. The monomers are fermented by primary fermenters to short-chained fatty acids (acetate, propionate, and butyrate) and to alcohols, h2 and. H2 is removed by methanogens, along with acetate. The key enzyme of this pathway is hexulose p-synthase . the sugar rearrangements require enzymes of the pentose phosphate pathway: the production of the pathway, acetyl-coa is used as the starting point for making new cell material. No, or n2o: can be detrimental anoxic conditions can develop if fields fertilized with potassium nitrate fertilizer becomes waterlogged.
