Document Summary

Until enzyme becomes saturated (max) it cannot increase any more no matter how much substrate you add. In anaerobic respiration, you have to have a constant supply of organic energy and electron source (electron acceptor: endogenous compound something within, accumulate fermentation, constant supply from the outside exogeneous, could be oxygen, organic or inorganic. Chemoorganic fueling processes: aerobic respiration, final electron acceptor is oxygen, anaerobic respiration, final electron acceptor is different exogenous acceptor such as no^3-, so4^2-, co2, Many different energy sources are funneled into common degradative pathways. Initial oxidation and degradation to pyruvate by the tca cycle: atp made primarily by oxidative phosphorylation. Amphibolic pathways: function both as catabolic and anabolic pathways. Important ones: embden-meyerhof pathway, pentose phosphate pathway tricarboxylic acid (tca) Glycolytic reactions: glucose, hexokinase, glucose 6-phosphate (freely reversible reaction, fructose 6-phosphate, phospho-fructokinase, fructose 1,6-bisphosphate, phosphoenolpyruvate (pep) (freely reversible reaction, pyruvate kinase, pyruvate.
