No, receptors do not catalyze reactions. Receptors on cell membranes or within cells bind to specific ligands, such as hormones or neurotransmitters, to initiate cellular responses but they do not themselves catalyze chemical reactions.

Enzymes. They are biological molecules that facilitate chemical reactions by lowering the activation energy required to convert substrates into products. Enzymes are highly specific, often catalyzing only one type of reaction.
Enzymes can catalyze reactions such as oxidation-reduction, hydrolysis, condensation, and isomerization. They can also facilitate reactions involving the transfer of functional groups or rearranging molecular structures.
Enzymes are the organic molecules that catalyze reactions in living systems. They act as biological catalysts by decreasing the activation energy required for a chemical reaction to occur. Enzymes are typically specific to particular substrates and can speed up reactions by many orders of magnitude.

Enzyme inhibitors can reduce the activity of enzymes by binding to them and preventing substrate binding or catalysis. They can be competitive (compete with substrate for the enzyme's active site) or non-competitive (bind to a site on the enzyme other than the active site). Inhibitors are of interest in drug development because they can be used to target specific enzymes involved in disease processes.
That would be an enzyme.
