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 two reactions defined as:
Reaction | Rate |
S1 + (2 * p1) S2 → S3 | k1 · S1 · S2 · C |
S3 → S1 + S2 | k2 · S3 · C |
The model contains one event that assigns a value to species S2:
Trigger | Delay | Assignments | |
Event1 | S1 < 0.75 | 0.95 | S2 = 1 |
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.0 | mole |
Initial amount of S2 | 2.0 | mole |
Initial amount of S3 | 1.0 | mole |
Value of parameter k1 | 0.75 | litre mole-1 second-1 |
Value of parameter k2 | 0.25 | second-1 |
Value of parameter p1 | 1 | dimensionless |
Volume of compartment C | 1 | litre |
The species values are given as amounts of substance to make it easier to use the model in a discrete stochastic simulator, but (as per usual SBML principles) their symbols represent their values in concentration units where they appear in expressions.
