Description

Introduction to enzyme kinetics Enzymes speed up a reaction by lowering the activation energy/delta G required

Enzymes are not used up when they catalyze a reaction

The rate of change from A to B would be equal to some rate constant k multiplied by starting material A The rate of a reaction is the speed that a reaction goes at

Total enzymes available is equal to the free enzyme E + enzyme bound to Substrate ES Products are usually thermodynamically stable so they don't really reverse

Swap out rate for rate constant

If Vo is equal to V max it means that a very high substrate conc , this means that the total enzyme conc is equal to ES

The speaker wrote that non-competitive inhibitors increase Km, but meant to say that Km does not change

Blue..enzyme without allosteric regulator Red...enzyme with a allosteric inhibitor Green...enzyme with an allosteric activator Affect Vo by effecting by Km...
