Q

How do drugs bind to receptors?

A

They receive (hence “receptors”) chemical information from other molecules – such as drugs, hormones or neurotransmitters – outside the cell. These outside molecules bind to receptors on the cell, activating the receptor and generating a biochemical or electric signal inside the cell.
