Question
Which of them have intracellular receptor ? (a) Peptide hormones(b) Steroid hormones(c) Iodothyroninesa & ba & ca, b & cb & c
Solution
The hormones that have intracellular receptors are Steroid hormones and Iodothyronines. So, the answer is b & c.
Here's why:
-
Peptide hormones: These are water-soluble and cannot pass through the plasma membrane of cells. Therefore, they bind to extracellular receptors.
-
Steroid hormones: These are lipid-soluble and can pass through the plasma membrane to bind with intracellular receptors.
-
Iodothyronines: These hormones, which include thyroid hormones, are also lipid-soluble and can pass through the plasma membrane to bind with intracellular receptors.
