The model contains one compartment called "compartment". There are two species called S1 and S2 and two parameters called k1 and k2. The model contains two reactions defined as:
Reaction | Rate |
S1 → S2 | k1 · S1 · compartment |
S2 → S1 | k2 · S2 · compartment |
The value of k2 is zero, which means the reverse reaction should occur at zero rate (i.e., not at all).
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.5 × 10−3 | mole |
Initial amount of S2 | 0 | mole |
Value of parameter k1 | 1 | second-1 |
Value of parameter k2 | 0 | 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.
Note: The test data for this model was generated from an analytical solution of the system of equations.
