- Researchers studying the SARS-CoV-2 virus, also known as COVID-19, have found that the virus is able to circumvent its host cell's normal defenses by leaving the cell via its lyso- somes rather than its normal secretory vesicles, as illustrated in the figure below. endoplasmic reticulum nucleus disrupted lysosomal functions Entry and egress of the SARS-CoV-2 virus A Golgi complex Which of the following best explains their findings? B lysosome (deacidified) С lysosome (acidified) B-coronavirus normal biosynthetic pathway egress via lysosomal trafficking SARS-CoV-2 inhibits lysosomes of its host cells by decreasing the pH within them.
