Internal Products Nutrients Stoichiometry or mass and energy balance Biology is not a graph.
Stoichiometry plus regulation Matrix of integers “Simple,” can be known exactly Amenable to high throughput assays and manipulation Bowtie architecture Vector of (complex?) functions Difficult to determine and manipulate Effected by stochastics and spatial/mechanical structure Hourglass architecture Can be modeled by optimal controller (?!?)
