It is axiomatic that for a substance to produce an effect in a biological organism, there must be some interaction between its molecules and certain counterparts in the organism. In the case of a hormone, the substance is made by the organism itself, and it is there to control specific functions. To have any value, therefore, these counterparts must be able to interact with the hormone only, and not with other substances, including other hormones, which may be present. In other words, the counterparts - receptors - have a recognition characteristic. This would hold regardless of how the effect is achieved, or the nature of the effect.
