Document Summary
A measure of the hydrogen ion concentration ph= -log[h+] Concentration in moles/liter note: relationship with [oh], the sum of the ph and poh=14. Ex: originally: poh is increased by 10000 now: Structure: poh decreased by 4=3 ph= 11 ph=7, and poh= 7. Primary, secondary, tertiary, and sometimes quaternary structures as proteins. Function: organic catalysts: speed up the rate of a reaction, but are not used up during the reaction highly specific. Model of activity enzyme + substrate enzyme-substrate complex enzyme-product complex enzyme + product. Non-spontaneous: require free energy (endergonic- up hill ); reactants have less energy than products. If entropy increases, free energy decreases (all others remain constant) If enthalpy and entropy are opposite- graph goes either up or down- one way. If they are the same then you need to know numbers. Non-spontaneous: can occur only with outside help (energy) Size and shape of molecules (small and without complex shapes)
