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.
