This reaction scheme was analyzed as in Chapter 1 7 by the assumption 

 of a quasi-steady state. The conclusion of this analysis was that the 

 concentration of free radicals [^4H-] should be proportional to the square 

 root of the enzyme concentration. This relationship was confirmed 

 experimentally by measurements of electron-spin resonance at varying 

 enzyme concentrations. In order to carry out the experiments, it was 

 necessary to use a flow system to reduce the minimum time necessary 

 after mixing until observations were possible.
