abstract = {Metabolite or substrate channeling is a direct transfer of
metabolites from one enzyme to the next enzyme in a cascade.
Among many potential advantages of substrate channeling,
acceleration of the total reaction rate is considered as one
of the most important and self-evident. However, using a
simple model, supported by stochastic simulations, we show
that it is not always the case; particularly at long times
(i.e. in steady state) and high substrate concentrations, a
channeled reaction cannot be faster, and can even be slower,
than the original non-channeled cascade reaction. In
addition we show that increasing the degree of channeling
may lead to an increase of the metabolite pool size. We
substantiate that the main advantage of channeling likely
lies in protecting metabolites from degradation or competing
side reactions.},
