A
Blood vessels
4
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.
5
Q
Why do receptors ‘‘change shape’’ when bonding with hormones?
A
Allows the receptor-hormone complex to enter the nucleus and regulate cell activity.
Increase the variety of messages they send to cells
