What molecule binds to the receptor to start the reaction inside the cell?

Cells have proteins called receptors that bind to signaling molecules and initiate a response.
Different receptors are specific for different molecules. That means that they will respond only to that signal. Your eyes respond to light but your ears do not.
There are hundreds of receptor types found in cells, and varying cell types have different populations of receptors.

When a hormone molecule binds to a specific protein on the plasma membrane the protein it binds to is called?
... a receptor protein.
What 3 things can occur when a signal molecule binds to a receptor protein?
1. Change the permeability of membrane. 2. Form a Second messenger. (Amplifies the first signal inside the cell.) 3. Activates enzymes inside the cell. (speeds up reactions inside the cell=catalyze)
What receptor has a ligand that can cross the cell membrane that binds?
Intracellular
What binds to receptor molecules on the host cell membrane?
glycoproteins
Which drug binds to the same receptor sites as the endorphins?
Heroin
What is a molecule that acts as signal when it binds to a receptor?
Intracellular receptor
What binds to a signal molecule enabling the cell to respond to the signal molecule?
receptor proteins bind to signal molecules
When a signal molecule binds to a receptor protein the receptor protein may change the?
shape.
Why is it important that each receptor protein binds to only one signal molecule?
because every receptor has specific shape on it, which binds with specific molecule.
When a hormone molecule binds to a specific protein on the plasma membrane the protein it binds to is called?
... a receptor protein.
What is a molecule such as a neurotransmitter or a hormone that binds to a receptor called?
what are the characteristics of action potentials
When a signal molecule such as a growth hormone binds to a receptor protein in the plasma membrane it stays on the outside of the cell. How might the inside of the cell know that the signal has bound?
Due to a conformational change of the receptor protein....

How does a receptor in the membrane transmit a message to the cell?
Receptors detect a signal molecule and perform an action in response.
What receptor has a ligand that can cross the cell membrane that binds?
Intracellular
The effect of a drug that is an agonist is to?
An agonist binds to a receptor and stimulates it (turns it on). An antagonist binds to a receptor and blocks it from being activated by other molecules (turns it off).
What describes a drug target?
The molecule to which a drug binds.
