Enzyme conservation
= Enzyme conservation
{title2=$\sum_{j=0}^n C_j=E_0$}
When each <chemical reaction> only changes the state of one <enzyme> molecule, summing all enzyme-state <concentrations> gives a conserved total. For sequential complexes satisfying $\dot C_0=-R_1$, $\dot C_i=R_i-R_{i+1}$, $\dot C_n=R_n$, the sum telescopes to zero. Bound <substrate> must be included separately in <substrate> <mass conservation>.
