Fig. 4. Simulated profiles of the concentrations of intraflagellar materials (solid
lines) and dynein ATPase activity (broken lines; relative values) along
flagella. The simulation was executed based on the model by Tombes et al.
(Tombes et al., 1987). The
lengths of flagella were set to 40 µm (A,C) and 100 µm (B,D). The ATP
diffusion coefficients of 150 (A,B) and 60 µm2
s–1 (C,D) were used. The diffusion coefficients of other
molecules are shown in Table 2.
In A and B, where we used D=150 µm2
s–1, we obtained almost the same results as those previously
reported by Tombes et al. (Tombes et al.,
1987).
