The model contains one compartment called "compartment". There are three species called S1, S2 and S3; one constant parameter called k2 and one varying parameter called k2. The model contains two reactions defined as:
Reaction | Rate |
S1 + S2 → S3 | k1 · S1 · S2 · compartment |
S3 → S1 + S2 | k2 · S3 · compartment |
The model contains one rule which defines that rate at which parameter k1 varies:
Type | Variable | Formula |
Rate | k1 | 0.2 |
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 | 1.7 | litre mole-1 second-1 |
Value of parameter k2 | 0.3 | second-1 |
Volume of compartment "compartment" | 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.
