The model contains two compartments named "compartment" and "compartment1". There are four species named S1, S2, S3 and S4 and three parameters named k1, k2 and k3. Compartment "compartment" contains species S1 and S2. Compartment "compartment1" contains species S3 and S4. The model contains three reactions defined as:
Reaction | Rate |
S1 + S2 → S2 + S2 | k1 · S1 · S2 · compartment |
S2 → S3 | k2 · (S2−S3) · compartment1 |
S3 + S4 → S4 + S4 | k3 · S3 · S4 · compartment |
The first reaction occurs entirely within "compartment", the second reaction occurs between a species in "compartment" and a species in "compartment1" and the third reaction occurs entirely within "compartment1".
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.0 | mole |
Initial amount of S2 | 1.0 | mole |
Initial amount of S3 | 0 | mole |
Initial amount of S4 | 0.1 | mole |
Value of parameter k1 | 0.75 | litre mole-1 second-1 |
Value of parameter k2 | 7.5 | second-1 |
Value of parameter k3 | 0.75 | litre mole-1 second-1 |
Volume of compartment "compartment" | 1 | litre |
Volume of compartment "compartment"1 | 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.
