The model contains one compartment called C. There are three species called S1, S2 and S3 and two parameters called k1 and k2. Compartment C is 0-dimensional. The model contains two reactions defined as:
Reaction | Rate |
S1 + S2 → S3 | k1 · S1 · S2 |
S3 → S1 + S2 | k2 · S3 |
The model contains two events that assign values to species S2 and S1:
Trigger | Delay | Assignments | |
Event1 | S1 < 0.65 | − | S2 = 1 |
Event2 | S3 > 1.2 | − | S1 = 1 |
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.0 | mole |
Initial amount of S2 | 2.0 | mole |
Initial amount of S3 | 1.0 | mole |
Value of parameter k1 | 0.075 | mole-1 second-1 |
Value of parameter k2 | 0.025 | second-1 |
In this example the compartment has its spatialDimensions attribute set to zero; i.e., it represents a point and therefore cannot have size or units. The species values must be treated as amounts and not concentrations.
