The model contains one compartment called "compartment". There are five species named S1, S2, S3, S4 and S5 and three parameters named k1, k2 and p1. The model contains two reactions defined as:

Reaction Rate
S1 → S3 k1 · S1 · compartment
S3 → S2 k2 · S5 · compartment

The model contains two rules:

Type Variable Formula
Assignment S4 func1(S3, p1)
Assignment S5 multiply(S4, p1)

The model contains two functionDefinitions defined as:

Id Arguments Formula
multiply x, y x · y
func1 x, y x/(1 + y)

The initial conditions are as follows:

Value Units
Initial amount of S1 1.0 mole
Initial amount of S2 0 mole
Initial amount of S3 0 mole
Initial amount of S4 0 mole
Initial amount of S5 0 mole
Value of parameter k1 0.1 second-1
Value of parameter k2 0.15 second-1
Value of parameter p1 2.5 dimensionless
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.
