What are cell receptor sites?

Every cell in your body has thousands of locations on its surface that serve as "mini" sense organs, called receptor sites. These receptor sites are actually proteins that are on the surface of each cell. They act as little receivers (or ears) that listen to the messages of the chemical messenger molecules as they float in the intercellular fluid surrounding every cell.

Another way to think of this is to consider each receptor site as a lock that is capable of receiving particular types of chemical messenger keys, called ligands (rhymes with "Bye Hands").

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
