Figure 9.

k_f’(t)=v_CK,f(t)/C_PCr(t) of the CK reaction as found with the multi-site exchange model with enzymatic rate equations (black) and the apparent k_f,ap’(t) as estimated by Bloch equation simulation of the ³¹P MRS saturation transfer method (red). The estimated values k_f,ap’(t) do not follow the cyclic variations of k_f’(t) and cannot be distinguished from the temporal average of k_f’(t) indicated by the blue dashed line.
