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.
