Petri nets are of advantage to applying the nets to simulation studies. Although an example of Condition
Event nets is described in this paper, they can be applied to higher classes of Petri nets such as Hybrid
Petri nets soundly [10]. A final goal is to reconstruct comprehensive knowledge of cellular functions into
a computer system on the basis of Petri net representation and ontology. For this goal, I have to further
investigate (1) practical transformation of existing data into a standardized formalization I propose, (2)
development of an algorithm to generate drawings of Petri net graphs, (3) specification of consistent
semantics for interrelation between signaling and metabolic pathways in cells, and (4) integration of
systematized cellular functions such as Gene Ontology [11] with biological pathways in Petri nets.
