What hormones act as intracellular receptors
Nonpolar hormones
What hormones act as extracellular receptors
Polar hormones
hormones that circulate freely are _____
Polar hormones
What type of hormone needs carrier proteins
Nonpolar hormones
Down regulation is
decreased cell receptors due to increase of the amount of circulating hormones
Up regulation is
increased cell receptors due to decrease of the amount of circulating hormones
