A modeling process to provide matter influx or efflux to a model, for example to replenish a metabolic network with raw materials (eg carbon / energy sources). Such reactions are conceptual, created solely for modeling purposes, and do not have a physical correspondence. Unlike the analogous demand (SBO:....) reactions, which are usually designated as irreversible, sink reactions always represent a reversible uptake/secretion processes, and act as a metabolite source with no cost to the cell. Sink reactions, also referred to as R_SINK_, are generally used for compounds that are metabolized by the cell but are produced by non-metabolic, un-modeled cellular processes.
