Question

spike proteins from the covid - 19 virus attach to the ace2 spike proteins of the host cell. which type of cell transport is the virus using to enter the host cell? pinocytosis phagocytosis exocytosis receptor - mediated endocytosis

Explanation:

The COVID - 19 virus attaches to specific ACE2 receptors on host cells. Receptor - mediated endocytosis is a process where cells take in substances that bind to specific receptors on their surface. Pinocytosis is non - specific uptake of extracellular fluid, phagocytosis is for large particles by specialized cells like macrophages, and exocytosis is for releasing substances out of the cell.

Answer:

receptor - mediated endocytosis
