The model contains one compartment called C. There are two species called S1 and S2 and two parameters called k1 and k2. The model contains one reaction defined as:
Reaction | Rate |
→S1 | C · k2 · S2 |
The model contains one rule:
Type | Variable | Formula |
Algebraic | n/a | S1 + S2−k1 |
The model contains one initialAssignment that assigns the initial value for parameter k1:
Variable | Formula |
k1 | 1 |
Note: InitialAssignments override any declared initial values. In this case the value from the initialAssignment is consistent with the value attributed to k1 by the model definition.
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 0.5 | mole |
Initial amount of S2 | 0.5 | mole |
Value of parameter k1 | 1.0 | mole litre-1 |
Value of parameter k2 | 1 | second-1 |
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.
