Component: Ca

$d Ca d time = k1_CaParv − k1 Ca Parv$

Component: Parv

$d Parv d time = k1_CaParv + k2_MgParv − (k1 + Ca + Parv) (k2 + Mg + Parv)$

Component: CaParv

$d CaParv d time = k1 Ca Parv − k1_CaParv$

Component: Mg

$d Mg d time = k2_MgParv − k2 Mg Parv$

Component: MgParv

$d MgParv d time = k2 Mg Parv − k2_MgParv$
