Below are the model equations defined by the class. First, an equation
accounting for uptake of glucose in solution by the yeast population, with
a potential correction term for osmotic back-flow from the cells:

The class accounted for yeast population growth using a per-capita growth model, with growth rates inhibitted by the presence of alcohol:

Finally, production of alcohol as a waste product must be accounted for using a proportionality-to-respiration argument:

Together, equations (6 - 9) form a complete model for the yeast-sugar system.
