what actually happens when a molecule activates a receptor vs when an inhibitor molecule just blocks it?

How is it that two different molecules can fit into a slot when one causes something to happen and the other just sits there doing nothing?

Extra question: what mechanism cleans up the inhibitor? Let’s say with an SSRI?

Regarding your extra question, most drugs are carried in the blood to the liver where they are broken down or modified to form more water soluble products that can be easily removed in the urine. The reason SSRIs can’t be taken with some medication is because they inhibit certain liver enzymes. This causes drugs that are normally modified by the enzyme to remain in the body for longer and at higher concentrations which can cause toxic effects.
