Document Summary
Chemical equilibrium: ok, now we have a dissociation reaction, ga g + a, [g] [a]/[ga] = keq which again does not change. These individual reactions do not reach equilibrium, but instead reach a steady state. Evolutionary benefits of steady state reactions: aa < 6 b"s < 4 c"s, why would cells need to perform chemical reactions this way, something about so they do not become poisonous. G: when a reaction is pushed away from equilibrium, the free energy g of the system increases, at chemical equilibrium, g = 0, when g = 0, no work can be done. If g is negative, the forward reaction will occur spontaneously, and energy will be released. Phosphate tail: the structure of the atp molecule is what makes it such an efficient energy source. (form dictates function), the 3 phosphate groups all located next to each other have negative charges. Like charges repel: the phosphate tail is like a compressed spring.
