Enzyme Kinetics

The rate of a reaction depends upon:

  • The ‘speed’ of a single reaction, specified as the rate constant, k
  • The number of reactions occuring, specified by the substrate concentration

We know this from our rate equation, Rate = k[Substrates].

So how do Enzymes speed up (or slow down reactions)?

Enzymes change k by decreasing the activation energy.
