This model contains one 0-dimensional compartment called "compartment". There are four species, S1, S2, S3 and S4, and two parameters, k1 and k2.
The model contains a function called "multiply" that takes two numerical arguments and multiplies them:
Id | Arguments | Formula |
multiply | x, y | x · y |
The model contains two reactions defined as:
Reaction | Rate |
S1 + S2 → S3 + S4 | multiply(k1, multiply(S1, S2)) |
S3 + S4 → S1 + S2 | k2 · S3 · S4 |
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.0 × 10−4 | mole |
Initial amount of S2 | 1.0 × 10−4 | mole |
Initial amount of S3 | 2.0 × 10−4 | mole |
Initial amount of S4 | 1.0 × 10−4 | mole |
Value of parameter k1 | 0.75 × 104 | mole-1 second-1 |
Value of parameter k2 | 0.25 × 104 | mole-1 second-1 |
In this example, the compartment has its spatialDimensions attribute set to
a value of zero; i.e., the compartment represents a point, and therefore
cannot have a value for the size
or units
attributes. The quantities
of species located in the compartment must be treated as amounts and not
concentrations.
