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 + S2 → S3 | k1 · S1 · S2 · C |
S3 → S1 + S2 | k2 · S3 · C |
The model contains one rule which must be used to determine the value of compartment C:
Type | Variable | Formula |
Algebraic | n/a | C − 0.75 |
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.0 × 10−1 | mole |
Initial amount of S2 | 2.0 × 10−1 | mole |
Initial amount of S3 | 1.0 × 10−1 | mole |
Value of parameter k1 | 7.5 | litre mole-1 second-1 |
Value of parameter k2 | 0.25 | second-1 |
Volume of compartment C | undeclared | 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.
