The model contains one compartment called C. There are three species called S1, S2 and S3 and two parameters called k1 and k2. The model contains one reaction defined as:
Reaction | Rate |
S1 → S2 | C · k2 · S1 |
The model contains one rule which assigns value to species S3:
Type | Variable | Formula |
Assignment | S3 | k1 · S2 |
In this case the initial value for species S3 must be calculated by the assignmentRule. Note that since this assignmentRule must always remain true, it should be considered during simulation.
The model contains one event that assigns a value to species S2:
Trigger | Delay | Assignments | |
Event1 | S1 < 0.25 | 1 | S2 = 0.75 |
The initial conditions are as follows:
Value | Units | |
Initial concentration of S1 | 1 | mole litre-1 |
Initial concentration of S2 | 0 | mole litre-1 |
Initial concentration of S3 | undeclared | mole litre-1 |
Value of parameter k1 | 0.75 | dimensionless |
Value of parameter k2 | 2.5 | second-1 |
Volume of compartment C | 2.5 | litre |
