The model contains one compartment called "compartment". There are two species called S1 and S2; two constant parameters called k2 and k3 and one varying parameters called k1. The model contains one reaction defined as:

Reaction Rate
S1 → S2 k1 · S1 · compartment

The model contains one rule that determines the value of parameter k1:

Type Variable Formula
Rate k1 add(k2, k3)

The model contains one functionDefinition defined as:

Id Arguments Formula
add x, y x + y

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 0.2 second-1
Value of parameter k3 0.3 lsecond-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.
