The model contains one compartment called "compartment". There are four species named S1, S2, S3 and S4 and two parameters named k1 and k2. Compartment "compartment" is 2-dimensional. Both species S3 and S4 are labeled as an SBML boundary species. The model contains two reactions defined as:
Reaction | Rate |
S1 + S2 → S3 + S4 | k1 · S1 · S2 · compartment |
S3 + S4 → S1 + S2 | k2 · S3 · S4 · compartment |
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.0 × 10−4 | mole |
Initial amount of S2 | 1.0 × 10−4 | mole |
Initial amount of S3 | 2.0 × 10−4 | mole |
Initial amount of S4 | 1.0 × 10−4 | mole |
Value of parameter k1 | 0.75 × 104 | metre2 mole-1 second-1 |
Value of parameter k2 | 0.25 × 104 | metre2 mole-1 second-1 |
Area of compartment "compartment" | 1 | metre2 |
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.
