Answer #1

Answer


Membrane bound receptors

Intracellular receptors
  • They are embeded or located on the cell membrane.
  • They are present in the cytoplasm or attached to nucleus of the cell.
  • They transport water-soluble (peptide) hormone.
  • They transport lipid-soluble (steroid) and thyroid hormones.
  • Binding to these receptors activates G protein and second messenger system.
  • Binding to these receptors activates gene transcription.
  • The hormones transported by membrane bound receptors include : Insulin, glucagon, grwoth hormone, tropic hormones.
  • The hormones transported by intracellular receptors include : Testosterone, thyroxine, cortisol.
