Fig. 9.

Top left graphs of the relative numbers of occupied (N), internal (R _i) and empty pits (N ₀), together with the numbers of receptors occupied by LDL (), VLDL-2 and VLDL-3 particles ( and , respectively), plotted against time. Lower left graphs of extracellular, and internalised LDL and VLDL particles (L _e, V _2e, V _3e, L _i, V _2i and V _3i) plotted against time. Lower right: graphs of bound LDL and VLDL (ψM _L, φM ₂, χM ₃) together with internal cholesterol level (C), again plotted against time. Parameter values: in all cases W = 3, k _L = k _Lc, k ₂ = k _2c/2, k ₃ = k _3c/2; All other parameter values are as in Table 3
