Document Summary

Flux is the rate of the overall pathway, describes how many molecules of substrate are converted to product. Le chatelier"s principle: equilibrium = most stable state, disturbances in the equilibrium => the system moves back to equilibrium, disturbances: removal or addition of reactant or product, changes in temperature or pressure. If a product is continuously removed, a reaction can keep going towards products. When you consider a reaction as a population of molecules, a represents the forward; b = backwards. Equilibrium state a characteristic of a reaction of either a or b. a certain ratio of a and b. Principle: if you disturb that equilibrium, the system will strive to go back to the equilibrium such that of temperature/pressure. However, in the body, we are more concerned with disturbances through the removal or addition of a reactant or product. You add more a"s the reaction will go into the direction that will move it back into equilibrium.
