Think-Pair-Share Questions

1. Animal viruses adsorb to receptors on the cytoplasmic membrane of host cells.

Why would our cells possess receptors that viruses could adsorb too?

2. When we vaccinate against viral infections such as measles, mumps, rubella, poliomyelitis, and chickenpox, we inject an attenuated or inactivated form of the virus. The body responds by making antibodies that coat the surface of that virus by binding to its surface proteins or glycoproteins.

Briefly describe two ways this may prevent future infections with this virus.
