The model contains one compartment called C. There are four species called X0, X1, T and S1 and one parameter k. The model contains two reactions defined as:
Reaction | Rate |
X0 → T | C · k · X0 |
T → X1 | C · k · S1 |
Reaction X0 → T defines one local parameter k. Reaction T → X1 defines another local parameter k. Note that these parameters have a scope local to the defining reaction.
The model contains one rule:
Type | Variable | Formula |
Algebraic | n/a | (1 + k) · S1 − T |
The initial conditions are as follows:
Value | Units | |
Initial amount of X0 | 1 | mole |
Initial amount of X1 | 0 | mole |
Initial amount of T | 0 | mole |
Initial amount of S1 | 0 | mole |
Value of parameter k | 2.5 | dimensionless |
Value of local parameter k | 0.1 | second-1 |
Value of local parameter k | 0.375 | 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.
