“…The kinetic effects resulting from changes in the medium ionic strength on reactions involving trypsin or α-chymotrypsin are different. The reaction rate increases continuously as the ionic strength increases with α-chymotrypsin. …”

“…We show in this work that through numerical solution of the Poisson-Nernst-Planck equations, diffusion-reaction processes can be studied at a variety of conditions including realistically concentrated solutions, high ionic strength, and certainly with non-equilibrium charge distributions. Reaction rate coefficients for the acetylcholine-acetylcholinesterase system are predicted to strongly depend on both ionic strength and substrate concentration. …”

“…Detailed reaction steps were analyzed along with their reaction rate constants. RESULTS: Most of the O-base oxidation reactions for this alanine peptide are exothermic except for the bond-breakage of the C(α)-N bond to form hydroperoxy alanine radical. …”

“…The results show that the reaction rate is limited by diffusion and is much slower with the laminar flow pattern, whereas the reaction is completed more quickly in the segmented flow due to better mixing.…”

“…Furthermore, we found that the catalytic activity of LFP-C could be further increased by increasing the specific surface area. The reaction rate constant of the hydrothermally synthesized LFP microcrystals (LFP-H) is at least 18 times higher than that of magnetite nanoparticles even though the particle size of LFP is far larger than magnetite nanoparticles. …”

“…Furthermore, our examples illustrate a delicate interplay between: (i) the rate at which the domain elongates, (ii) the diffusivity associated with the spreading density profile, (iii) the reaction rate, and (iv) the initial condition. Altering the balance between these four features leads to different outcomes in terms of whether an initial profile, located near x = 0, eventually overcomes the domain growth and colonizes the entire length of the domain by reaching the boundary where x = L(t).…”

“…The method consists of plotting experimental data as [Formula: see text] versus the reciprocals of the substrate concentrations, where V(max) represents the maximal velocity. The reaction rate constant of enzyme–substrate–inhibitor complex [Formula: see text] can be calculated from the ordinate intercept of the linear relationship between [Formula: see text] and the reciprocal of the substrate concentrations at the higher and inhibitory concentrations of the substrate: partial type [Formula: see text] of the substrate inhibition gives straight lines intersecting with the ordinate at [Formula: see text] , whereas complete substrate inhibition [Formula: see text] yields straight lines converging on the origin. …”
