where β is the factor that accounts for the different
dimensions of the electrodes (here 0.119). However,
IP(sulfite) > βID(sulfite) for the reasons given above. The sulfite
removed by the processes at the enzyme is twice the
amount oxidized by the enzyme (as 1 mol sulfite reacts with
1 mol hydrogen peroxide) and in the linear region of the
enzyme reaction, this is proportional to the bulk concentration
of sulfite. As the sulfite current is proportional to the
concentration of sulfite at the detector electrode
