1. A reaction model is described as the following: \[ A \stackrel{\mathrm{k}_{1}}{\longrightarrow} B \stackrel{\mathrm{k}_{2}}{\longrightarrow} C \] We used this type of model to simulate enzymatic breakdown of polymeric food molecules and subsequent absorption of the monomers into the blood. This model can also be used to simulate release of drug from a pill or capsule in the blood and subsequent absorption of the drug by human brain tissue, and to simulate injections of drug and subsequent drug elimination. Initial condition:CA=CA0,CB=0, andCC=0att=0. DeriveCBas a function ofCA0,k1,k2, andt.
