The "circuit diagram" of a biological process, complete with quantitative parameters, is known as a "kinetic model," and I think these are slowly growing in popularity. Quantitative reaction kinetic constants are quite hard to obtain, hence the qualitative "A raises B and lowers C, B raises D, C raises D" mess where even that simple sentence I told you gives you nothing about the relationship between A and D. I don't think anyone looks at a process diagram with zero known constants and says "that's the way that things should be," but at the same time, it's so difficult to tell what those constants are that the uselessly unconstrained diagrams are still, oftentimes, the best that can be done.
