Question

differentiate between exocytosis and the three types of endocytosis. 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? exocytosis pinocytosis receptor - mediated endocytosis phagocytosis

Explanation:

Exocytosis is a process of releasing substances out of the cell. Pinocytosis is the uptake of fluids and dissolved substances. Phagocytosis is the engulfing of large particles. Receptor - mediated endocytosis is a specific type of endocytosis where molecules bind to receptors on the cell surface. The COVID - 19 virus attaches to specific ACE2 receptors on the host cell, which is characteristic of receptor - mediated endocytosis.

Answer:

receptor - mediated endocytosis
