Document Summary

Adp+pi atp: at equilibrium, there is much more reactant than product, respiration displaces the reaction to the right to maximize -delta g to maximize work that can be done. Objectives: describe how fermentation allows recycling of. Nad+ allowing continued catabolism: define how light energy is used to make atp using electron transport, describe link b/n products of photosynthesis and fixation of co2 in calvin cycle. Oxidative phosphorylation requires o2 what happens when there is none: anaerobic respiration, many microbes have respiratory chains that pass e- to e- acceptors other than. O2: alternate e- acceptors include sulfate, nitrate, co2, electron transfer to acceptor is used to do work of atp synthesis, example, rotten egg smell at beach from hydrogen sulfide, produced by sulfate reducing bacteria. If mitochondria isn"t working well then cells can"t make energy so more messed up mitochondria is made: results in multi-organ dysfunction because you can"t make enough atp to do work.
