The model contains one compartment called C. There are four species called S1, S2, S3 and S4 and three parameters called k1, k2 and k3. The model contains two reactions defined as:
Reaction | Rate |
S1 → S3 | k1 · S1 · C |
S3 → S1 | k2 · S3 · C |
The model contains two rules:
Type | Variable | Formula |
Assignment | S4 | k3 · S1 |
Rate | S2 | k2 · S3−k1 · S1 |
Note that in this case the initial value declared for species S4 is inconsistent with the value calculated by the assignmentRule. The calculated value should be used.
The initial conditions are as follows:
Value | Units | |
Initial concentration of S1 | 1 × 10−5 | mole litre-1 |
Initial concentration of S2 | 1.5 × 10−5 | mole litre-1 |
Initial concentration of S3 | 1 × 10−5 | mole litre-1 |
Initial concentration of S4 | 5 | mole litre-1 |
Value of parameter k1 | 0.015 | second-1 |
Value of parameter k2 | 0.5 | second-1 |
Value of parameter k3 | 1.5 | dimensionless |
Volume of compartment C | 1.4 | litre |
