Question

In viruses, the surface glycoproteins: a. allow the host cell to break free from the virus. b. allow the virus to break free from the host cell. c. trigger chemical signals in the interior of the virus to tell it when to let water out or take water in. d. bind to receptors on the surface of the host cell and allow the virus to enter. e. both b and d are correct.

Answer 1

Viruses enter a host cell when the host cell recognizes and binds the glycoproteins on the virus's surface, then take in the virus by phagocytosis. Thus, d. is the correct answer.
