The primary receptor for caffeine on the cell membrane is the adenosine receptor. Caffeine acts as a non selective antagonist at the A1 and A2A receptors, so it has the opposite effect of adenosine, acting as a stimulant and increasing heart rate.
The first order sensory neuron can sometimes be a sensory receptor because it is what sends the signal to the brain from the receptor. The second order goes from the brainstem to the thalamus.

Actually, in order to stimulate fruit growth you can strike your tree or you can have another fruit sit on top of your tree and that should stimulate growth in your "fruit".
The only way to change the pA2 would be to alter the nature of the receptor, because the pA2 is essentially a measurement of the affinity of the antagonist drug for the receptor. So, in order to change this value, one would need to change the receptor in a way that changes the binding affinity of the drug.

A receptor is generally a recognition molecule situated on the surface of a cell. A receptor is a molecule that is sensitive to a particular signal and is also able to transmit information to the nucleus in order to control gene regulation. In order for a receptor to function, it must first be activated. The binding of a ligand to the receptor places the receptor in the activated state. Once the receptor is activated, it is now able to transmit signal to the interior of the cell.
the antigen must bind to the receptor
