Simulation 1: chemotaxis towards a chemical sensed by both sensory clusters. (a) Exemplar trajectory in simulation box. (b) Experienced chemical concentration. (c) The stopping probability contributed by the transmembrane sensory pathway gradually increases as chemical concentration increases. (d) The stopping probability resulting from the cytoplasmic sensory cluster increases more significantly as the chemical concentration increases. (e) The integrated stopping probability eventually approaches 1 as the cytoplasmic sensory cluster almost saturates. (f) The distribution of 50 simulated bacteria along x-axis shows that the bacteria favour medium attractant concentrations. (g) Corresponding endpoints of bacteria. (h) Attractant concentration increases linearly in positive x-direction. (Online version in colour.)
