The critical spherical shell in enzymatic fast reaction systems.

As we go more deeply into the theoretical analysis and actual calculations for enzymatic fast reaction systems, the concept of the critical shell would naturally be confronted with. In this paper, a formula is presented to estimate the thickness of the critical shell. An on such a basis, we have made calculations and discussed the influences of various factors such as short-range force, long-range force, activation energy and cavity-active site upon the thickness of the critical spherical shell.
