The model contains three varying parameters called S1, S2 and S3 and two constant parameters called k1 and k2. (Note that indeed S1, S2 and S3 are parameters and not species in this model.)
The model contains three rules defined as:
Type | Variable | Formula |
Rate | S1 | k2 · S3 − k1 · S1 · S2 |
Rate | S2 | k2 · S3 − k1 · S1 · S2 |
Rate | S3 | k1 · S1 · S2 − k2 · S3 |
The model contains two events, that assign value to parameters S2 and S1 respectively, defined as:
Trigger | Delay | Assignments | |
Event1 | S1 < 0.75 | − | S2 = 1 |
S1 = 1 |
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.0 | any |
Initial amount of S2 | 2.0 | same as S1 |
Initial amount of S3 | 1.0 | same as S1 |
Value of parameter k1 | 0.75 | (unit of S1)-1 second-1 |
Value of parameter k2 | 0.25 | second-1 |
