The kinetics of the general enzyme-catalyzed reaction (equation 10.1-1) may be simple or complex, depending upon the enzyme and substrate concentrations, the presence/absence of inhibitors and/or cofactors, and upon temperature, shear, ionic strength, and pH. The simplest form of the rate law for enzyme reactions was proposed by Henri (1902), and a mechanism was proposed by Michaelis and Menten (1913), which was later extended by Briggs and Haldane (1925). The mechanism is usually referred to as the Michaelis-Menten mechanism or model. It is a two-step mechanism, the first step being a rapid, reversible formation of an enzyme-substrate complex, ES, followed by a slow, rate-determining decomposition step to form the product and reproduce the enzyme ... 

Two types of models have been applied to the mechanical strength of paper. The first assumes paper to be a continuous network of hydrogen bonds with no other type of bond contributing to its mechanical properties, and the second describes its mechanical strength in terms of a combination of fibre strength and fibre-to-fibre bonds. 

Membranes provide sufficient mechanical strength to support the column of the internal reference solution in macro models (1) as well as resisting sheer forces in flowing systems. 

These microcracks may have some effect in terms of mechanical strength when these cokes are processed into artificial graphite electrodes. However, no significant difference in strength between graphitized test pieces obtained from actual electrodes under the new and traditional method was found. An optimum commercial new process system has been studied by using a model calciner pilot plant.
