$2\mathrm{.}6.$ Write equations for the small protein system in the$$signaling cascade of Figure $2\mathrm{.}7.$ Model each process$$as a rate constant times the concentration of the$$variable involved. For instance, the phosphorylation$$of P$0$ toward P$1$ should be formulated as r$01$P$0.$Begin with P$0=$ P$1=$ P$2=1$ and set all rate$$constants to $0\mathrm{.}5.$ Implement the system in a$$software program and simulate it$.$ Explore the$$dynamics of the system by changing the initial$$values of P$0,$ P$1,$ and P$2.$ Discuss the results.$$Now change the rate constants one by one or in$$combination$,$ until you develop a feel for the$$system$.$ Discuss the results and summarize your$$insights into the system.
