Giovanni Cummings · Answer 1

This is because the active site of the receptors on the cell and the hormone are akin to lock and key respectively. The conformations of the receptor’s active site and the hormone allow them to interlock with specificity. The receptor (which is a transmembrane protein) is connected to second messengers inside of the cell that triggers a biochemical cascade in response to the hormone.
