In the following paragraphs, we will compare this simple integrative approach to kinetic modeling using three different approaches, which are two-site exchange differential model, two-site exchange integral model, and multisite exchange integral model.
Hence, when passing from 2SIM to a multisite exchange integral model (MSIM), the PYR input function (4)--represented in its differential form--needs to include all of the metabolic exchange rates:
The asymptotic behavior at the Bethe Ridge was used to simplify the calculation and to provide values for the exchange integral.
