Question

Which of the following statements regarding exocytosis is true? it involves budding through the plasma membrane exocytosis provides a virus with its envelope it involves fusion of a secretory vesicle with the plasma membrane exocytosis involves release of a virus from the endosome all the statements are true Which of the following statements correctly describes viral endocytosis via caveolae? the virus interacts with receptors located in lipid rafts uptake involves the formation of clathrin coated pits the endocytic vesicle delivers the virus to the endosome the virus is released from the endosome at low pH all of the above

Explanation / Answer

Answer 1 :
Exocytosis describes the process of secretory vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell
The plasma membrane expands as a result of exocytosis.
Viruses with no viral envelope enter the cell through endocytosis, so exocytosed without envelope.

So answer is

c) it involves fusion of a secretory vesicle with the
plasma membrane

Answer 2:
Caveolae are one source of clathrin-independent raft-dependent endocytosis. The caveosome is an endosomal compartment with neutral pH

So answer is
a) the virus interacts with receptors located in lipid rafts
