This image shows three stages of endocytosis of a SARS-CoV-2 virion. First, the virion attaches its spike protein to an ACE2 embedded in a cell membrane. The cell then encloses the virion with part of its membrane and brings it inside. The enclosure is then merged with the membrane of the virion, and the content of the virion is ejected into the cell's cytoplasm.
