Why is it a good strategy for a microbe to adhere to a receptor that plays a critical function for a host cell?
A)It ISN'T a good strategy-host cells could shift to a backup receptor and shut down production of the main receptor,preventing infection.
B)If it's a receptor the cell MUST use,it doesn't have a backup system in place to switch to-so,even though it makes it susceptible to infection,it HAS to put that target out there.This benefits the microbe.
C)Microbes need to evade detection and elimination by the immune system-if they adhere to a receptor that plays a critical function,they are less likely to trigger destructive immune responses.This would be similar to using a hostage as a shield in a police-standoff situation.
D)It ISN'T a good strategy-by binding to receptors,microbes will be phagocytosed by cells and destroyed within them.

If the receptor plays a critical function for the host cell and there is no backup system in place, then the microbe will have an advantage in targeting that receptor. This increases the probability of successful infection.
