Do Hormones Diffuse Through Cell Membrane
Cortisol is a steroid hormone produced by the adrenal glands. Lipid-soluble hormones diffuse through the plasma membrane to enter the target cell and bind to a receptor protein.

The hormone binds to its receptor in the cytosol forming a receptorhormone complex. Lipid insoluble hormones bind to receptors on the outer surface of the plasma membrane via plasma membrane hormone receptors. Unlike steroid hormones lipid insoluble hormones do. Except for thyroid hormones which are lipid-soluble all amino acidderived hormones bind to cell membrane receptors that are located at least in part on the extracellular surface of the. Free steroid molecules passively diffuse through a cells. Amino acid-derived hormones with the exception of thyroxine and polypeptide hormones are not lipid-derived lipid-soluble a...
