Question

What hormones has intracellular receptors?

Answer 1

Steroid hormones

Step-by-step explanation:

Steroid hormones are fat soluble and they can easily diffuse out of the cell through the membrane. When these hormones are secreted, they attach to the transport protein and remain in soluble state.

These hormones enters the targeted cell by piercing through their plasma membrane where they attach with the intracellular receptors within the nucleus or cytoplasm. The complex of hormone and intracellular receptor regulate the synthesis of mRNA and hence act as transcription regulator.

Answer 2

Lipid soluble hormones have intracellular receptors.

Step-by-step explanation:

Lipid soluble hormones can cross the core of the membranes of their target cells made up of non-polar tails of the phospholipids. Therefore, these hormones mostly have intracellular receptors. Binding of these hormones to their receptors alters the gene expression. Steroid hormones such as aldosterone, cortisol, androgens and thyroid hormones such as T3 and T4 are some examples of the lipid-soluble hormones. Water-soluble hormones can not cross the core of the membranes and have cell surface receptors.
