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? click or tap a choice to answer the question. exocytosis phagocytosis pinocytosis receptor - mediated endocytosis

Explanation:

The COVID - 19 virus spike proteins bind to ACE2 receptors on host cells. Receptor - mediated endocytosis is a process where specific molecules bind to receptors on the cell surface, triggering the cell to engulf the molecules. Exocytosis is the process of expelling substances from the cell. Phagocytosis is when cells engulf large particles. Pinocytosis is the non - specific uptake of fluids. Since the virus binds to specific ACE2 receptors to enter the cell, it is receptor - mediated endocytosis.

Answer:

receptor - mediated endocytosis
