A SARS-CoV-2 virion (monster egg, inside of which is a monster representing viral RNA) touches host-cell plasma membrane (blue bending ground) producing tensile force (children’s pulling), which not only strengthens spike–ACE2 (children) recognition, but also accelerates the S1/S2 separation to boost viral fusion machinery. See page 1047-1060 by Wei Hu et al. for details.
