Monte Carlo simulation with varying value of mobility and aggregation level of NRO. (A) If all NRO are mobile with the same speed as the reactant and have the same size like it, the reactants in a cell show nearly a normal diffusion independent from the level of crowdedness. If the mobility of NRO is lower than the reactant diffusion in the reaction space, the reactants show anomalous diffusion as observed by FCS experiments. The different lines show the results produced by the different levels of crowding (0–70% of the volume is occupied by NRO). (B) Mobility of NRO is the same as the mobility of the reactant while the size is varied.
