The model contains one compartment called "compartment". There are three species named S1, S2 and S3 and two parameters named k1 and k2. The model contains one reaction defined as:
Reaction | Rate |
S1 → S2 | compartment · k2 · S1 |
The model contains one rule which assigns value to species S3:
Type | Variable | Formula |
Assignment | S3 | k1 · S2 |
In this case there is no initial value declared for species S3 and thus it must be calculated by the assignmentRule. Note that since this assignmentRule must always remain true, it should be considered during simulation.
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 0.1 | mole |
Initial amount of S2 | 1.5 × 10−2 | mole |
Initial amount of S3 | undeclared | mole |
Value of parameter k1 | 0.75 | dimensionless |
Value of parameter k2 | 50 | second-1 |
Volume of compartment "compartment" | 0.08 | 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.
