Why Is It a Good Strategy for a Microbe to Adhere

question 54

Multiple Choice

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.
