The simulations show the impact of interchanging the lifetimes of activated rhodopsin and PDE. The phosphorylation, arrestin binding, and transducin activation rates are given by Eqs. 48–50 with ωλ = ωact = 0.1, Np = 6, k3 = 50 s−1. For τ = (0.2, 1) s, the rates λN and kact(N) are (48.2, 9.6) s−1 and (1274, 1067) s−1.
