Metabolic Pathways
It is the pathway to show how to generate energy and remove
metabolite for a body.
Signal Transduction Pathways
It is the pathway to show how to control the behaviors of a cell
in terms of time and location with the signals like hormones.
Regulatory Pathways (Gene Regulatory Network)
It is the pathway to show how to adapt to the change of environment
based on the principles encoded in hereditary materials (e.g. DNA).

To understand the mechanism of organism
• It provides the guidance for biologists to design experiments.
• It helps pharmacist to design drugs easier.
• It makes us know the difference of mechanism between species.
Enable us to do the simulation
• It saves time and money for biologists to do experiments.
• It predicts the behaviors by a special treatment for an organism.
• It waives the dangers to try a new drug on patients.
