โœฆ Synopsis

Evidence is presented to show that the presence of a channelled reaction branch in a coupled two-enzyme reaction leads to a slower overall relaxation of the system towards steady state following perturbations of the reaction conditions. A predominant part of the total reaction flux change resulting from perturbations may be governed by transients that are more rapid in the presence than in the absence of a channel, but only under specific conditions that are not likely to be of biological relevance.

## Abstract If the chemical rate constants of the initial reaction steps are large, any observed value of these constants may be affected by the mixing process. To investigate the effect of mixing efficiency on reaction kinetics we use two previously analyzed reaction systems, namely the glutamic a
