Network : A R1 B R2 C R3 D R4 A
1. Without doing any calculations can you identify any conservation laws or sets of reactions which will leave the state unchanged?
2. In MATLAB construct the petri net for this system by defining s, r, Wsr, Wrs and m (assume the state m contains one token in species A only).
3. Use these to calculate reaction matrix A and stoichiometry matrix S
4. Calculate the P and T invariants for this system and comment on their meanings. Did you identifiy them in part (a)?
5. Repeat for this network (There is a B and a C coming from R1):
(This network is A R1 B R2
