Experimental data and available knowledge on enzyme mechanics are used in constituting amathematicalmodel. Themodels are either in the formof linearornonlinearordinarydifferentialequationsorpartialdifferentialequations. Theseequationsare composedofkineticparameters suchaskinetic rate constants, initial rates, andconcentrationsof enzymes. Thenonlinearnatureof enzymatic reactions anda largenumberofparametershave causedmajor issueswith regard toefficient simulation of those reactions. In thiswork,anenzymatic systemthat includesMichaelis-Mentenand PingPongkinetics ismodeled in the formof differential equations. These equations are solvednumerically inwhich the systemparameters are estimated.Thenumerical results arecomparedwith theresults fromanexistingworkin literature.
