-## [Chemical cross coupling](@id basic_CRN_library_cc)
-In chemistry, [cross-coupling](https://en.wikipedia.org/wiki/Cross-coupling_reaction) is when a catalyst combines two substrates to form a product. In this example, the catalyst ($C$) first binds one substrate ($S₁$) to form an intermediary complex ($S₁Cat$). Next, the complex binds the second substrate ($S₂$) to form another complex ($CP$). Finally, the catalyst releases the now-formed product ($P$). This system is an extended version of the M[Michaelis-Menten system presented earlier](@ref basic_CRN_library_mm).
