The Topology of Autocatalytic Feedback Patterns in Living Systems

10 The Topology of Autocatalytic Feedback Patterns in Living Systems 

Losses of catalyst which limit the catalytic turnover numbers to finite values. 

An autocatalyst must be obtained from some external reservoir by expenditures of matter (which especially in terrestrial plants may be quite substantial when secreting chelators to the rhizosphere for subsequent retrieval after metal trapping). 

A general balance for these processes may be constructed when certain contributions are considered
