define mechanism of hormone action

Mechanism of Hormone Action

  • Hormones exhibit their effects only after binding to their specific receptors located in the target tissues to form hormone-receptor complex.

  • Membrane-bound receptors: Present on the cell membrane of the target cell

  • Intracellular receptors: Present inside the target cell

  • This specific reaction leads to biochemical changes in the target tissue, and regulates its metabolism and physiological changes.
