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.

How would you change the pA2 for a drug-receptor pair?
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.

How do sensory receptors work?
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.
