Dan,

The above was an old thread, but I was reading some old Bulletin of Mathematical Biology journals I had bought awhile back and ran across something you might find interesting with regard to your CCP (coupled complementary processes).

 

In an article entitled "Towards an Optimal Design Principle in Relational Biology" by H.M. Martinez (BMB:26-4, 1964), regarding the (M,R) system he writes in his introduction:

"In the approach by R. Rosen for the relational representation of the metabolic aspects of unicellular organisms it is assumed that this physiological process is decomposable into a collection of two types of component processes. One type, collectively called the M components, stands roughly for the set of catabolic processes, while the other, consisting of the R components, can be interpreted as the anabolic part."

I had never considered the M & R processes in that light, nor do I recall recall Rosen mentioning it (so I don't know what his view would be). But I recall you asking once about the (M,R) model and complementary processes, and so I thought I'd just mention it to you. This is a somewhat different view than Don M.'s extended (M,R) model (http://www.people.vcu.edu/~mikuleck/cellmr.html) which includes additional explicit pathways to/from B to represent anabolic/catabolic pathways.
