Four aspects of membrane mobility in multivalent receptor/ligand binding discussed in this work: receptor mobility during (a) and before (b) binding, as well as binding‐dependent changes in the mobility of the receptor/ligand complex (c) and surrounding lipids (d). The thickness of the “movement” arrows indicates the magnitude of the diffusivity. Here, we do not discuss the flexibility of the ligand and assume the distance between its binding sites to remain unchanged throughout the binding process.
